How to run LIGO_LW <-> ILWD conversion test

This is a series of tests that exercises conversion of ILWD to LIGO_LW and vice versa by 2 user commands:

ILwd2Lw - converts ilwd file to xml
Lw2ILwd - converts xml file to ilwd

The LDAS APIs affected by this test are:

managerAPI: directs processing of the insertion user commands to the ligolwAPI and metadataAPI and returns the user command status to the user.

ligolwAPI:
- Converts ILwd file to xml via user command ILwd2Lw or xml to ilwd via Lw2ILwd.

Setup

Choose a directory to install the tests scripts.

The script files are:
LwIILwd.test - main driver script


        ilwdtypes.ilwd
        - ilwd file testing all ilwd types for database, with nullmasks

        ilwdtypes.xml
        - xml file with same data content as ilwdtypes5.ilwd

		
		Note: the nullmask attribute in ilwd is used to mark certain fields to be null so the database would not
		insert any data for that field if the ilwd was used in putMetaData.
		
        
Note: The above files should be installed on your local platform..


        Running the test
		The test should be run from your local platform, and run in the scripts directory.
		
		cd <scripts directory>

		
        Usage: LwIILwd.test >& LwIILwd.log & 		
		

		
Test Verification:
		The script does a comparision of the output file (ilwd or xml) against the input specified by -ingestdata option;
		if there is no mismatch the test passes.
