updated Pubmed branch with test for Controller; minor corrections to
controller, and pubmed integration test
Modified test com.recomdata.transmart.plugin.PluginModuleTests so that it does not set the, undefined, field 'version' on the test PluginModule object - test does not compile if this is included
added @Ignore to empty, hard-fail, test
Full complement of unit and integration tests for Pubmed service and controller - revised some of the test code - compiles, runs, passes (grails test-app Pubmed*)
