Database front-end package for the REST API.
Introduction:
-----------------------------------------------------------------------------------------------------------------------------------
Most of the functions and procedures that are contained within this package accept the following parameter values embedded within 
the p_json_parameters parameter:
  sessionId                   The sessionID of the restAPI client
  clientAddress               The IP address of the restAPI client
  userAgent                   The restAPI client's user-agent
Here is an example of a basic JSON parameter string:
  {"sessionId":"9YAZOHVGXQ0MFKCXYJWJZT5X61Z5O8LL", "clientAddress":"127.0.0.1", "userAgent":"..."}
  
Any exceptions to this general rule are noted within a specific function or procedure.
Each embedded parameter value is required unless noted otherwise.
JSON value keys are case sensitive.
Exception Handling:
-----------------------------------------------------------------------------------------------------------------------------------
Functions and procedures may return an exception upon detecting an error.  It is the caller's responsibility to handle the
exception in accordance to the expectations of the client.  While some clients may be able to process the exception directly, others
will expect an HTTP conformant error.  
The error code value associated with the exception may be Oracle specific or AsterionDB specific.  Valid AsterionDB error code 
values are between -20000 and -20999.
AsterionDB specific errors are raised and logged directly by the data-layer logic.  Oracle specific errors are not caught by 
data layer logic.  For Oracle specific errors it is the caller's responsibility to call object_vault_restapi.restapi_error in 
order to log the error  information to the AsterionDB error log. The data returned by restapi_error will contain a properly 
formatted error message.
There is a setting in the AsterionDB profile that enables extended error information. Enabling this option is very useful in 
development and debugging situations.

  function confirm_user_registration
  
  The confirm_user_registration function is the last step in the process of user registration.  Users can self-register for access

  a weblink to their primary email address.  This weblink will take them to a confirmation webpage that will require the user to
  log into the system in order to finalize their registration.
  
  New user registration is initiated by calling the register_new_user procedure.
  The confirmationToken can be checked for validity by calling the validate_confirmation_token procedure.
  
  This procedure is to be called after successfully establishing a session by calling create_user_session.  The user session will
  be blocked and can be unblocked by calling this procedure.

  function create_an_object
  
  The create_an_object function allows a client to create an object in AsterionDB.  This is akin to pre-creating an output file
  so that you can write data to it.  The create_an_object function will return a output file name.
  
  Embedded parameter values:
  
    sessionId                 See introduction
    clientAddress             See introduction
    userAgent                 See introduction
    
    source                    The original source path for the file.  This value is required and at a minimum must be a valid 
                              filename with an extension - path information is optional.
    creationDate              If specified, the original creation date of the source file.  This is useful when you want to record 
                              the creation date of the original file.  This value maps to object_versions.ingested_file_cdate.
                              This value is specified as a unix timestamp value.
    modificationDate          If specified, the original modification date of the source file.  This is useful when you want to 
                              record the modification date of the original file.  This value maps to 
                              object_versions.ingested_file_mdate.  This value is specified as a unix timestamp value.
    accessDate                If specified, the date that the original file was last accessed.  This is useful when you want to
                              record when the original file, in the context of it's origin, was last accessed.  This value maps
                              to object_versions.ingested_file_adate.  This value is specified as a unix timestamp value.
    programName               If specified, the name of the program that will be used to write the object to AsterionDB.
    versionedObject           The create_an_object function will, by default, create an object that is unversioned.  To create a
                              versioned object, set the versionedObject parameter to object_vault_restapi.OPTION_ENABLED.
    gatewayName               The DbObscura gateway that will be used to convey the file data into AsterionDB.                  
    accessMode                This value must be specified.  Use the constant values object_vault_restapi.WRITE_ACCESS or 
                              object_vault_restapi.READ_WRITE_ACCESS as appropriate for your needs.
    validUntil                This value, if specified, allows you to set the date at which the filename returned by this function
                              will expire.  This value is specified using the constants object_vault_restapi.VALID_FOR_AN_HOUR,
                              object_vault_restapi.VALID_FOR_A_DAY or as a unix timestamp value.
    accessLimit               The create_an_object function will, by default, return a filename that will allow the object to be
                              opened once.  To increase the number of times the filename can be used to open the 'file', set the
                              accessLimit value accordingly.  Use object_vault_restapi.UNLIMITED to disable the
                              access limit.
    enforcePidSecurity        Setting enforcePidSecurity to object_vault_restapi.OPTION_ENABLED instructs the DbObscura 
                              gateway to require that the process id of the program accessing the gateway to match, or be a 
                              descendent of the process that called create_an_object.
    enforceSidSecurity        Setting enforceSidSecurity to object_vault_restapi.OPTION_ENABLED instructs the DbObscura 
                              gateway to require that the database session that called create_an_object to still be active.
    enforceIpSecurity         Setting enforceIpSecurity to object_vault_restapi.OPTION_ENABLED instructs the DbObscura 
                              gateway to require that the IP address of the DbObscura gateway match the IP address of the
                              host machine used to call create_an_object.
  Embedded values in the returned JSON string value:

    newVersion                The newVersion parameter causes the create_uploaded_file function to either create a new object or to

  One can easily see that the file system organization implies that image001.dcm is part of the series 'series-0001' and the study

                              The maximum path depth is 5.  The proper array for subdirectoryKeywords would thus contain 5 elements.
