CompositeSequence domain data

1. Correct Composite file structure
2. Mandatory field
3. Field value format Field multiplicity
4. Field cardinality (-> a missing item checking)
5. Duplicate CompositeSequences(equal names) :
   Check every field of CompositeSequence data, should be identical
6. Correct mapping :
   Names in the « MAP »field must exist in the FeatureReporter file for Reporter, or in the CompositeSequence file (current file) for CompositeSequence
