Merge branch 'develop' into feature/BatchInject
added tests to the MetadataTest class for the new prompting methods.
Added new WS resources to deal with batch adding metadata. Get experiments from study acc; get lanes from sequencer run acc or from IUS acc; get samples from experiment acc, parent sample acc, child sample acc; get IUS from lane acc or sample acc
Changed metadata test to handle lane numbers
Added new methods to the metadata class to take advantage of the new resources. getting all sequencer runs, getting experiments from study acc, getting lanes from sequencer run acc, getting iuses from  lane acc or sample acc, getting samples from experiment acc, getting parent and child samples for samples
Fixed the tests prior to pull request. When creating a lane, the lane number is nnow required. Changed the Metadata objects appropriately. Added dummy tests in MetadataDBTest to mask the new tests in MetadataWSTest. Commented out the line that would allow the jar to find BatchMetadataInjection as a plugin since it is not done.
