In Metadata, implemented the method that unmarshall the data from a metadata parcel an return java entities. Add 2 new types of metadata (Boolean and Date) and fixed an issue in TimedText: the w3c standard specify a duration as well as the time to be played => added a duration field. In MetadataParserTest.java: Moved the util private methods at the bottom of the file. Added new tests for the getters (GETTERS section)
