Message:

Added new abstract plugin MetadataRead that defines can_process_this_file_for_metadata that MetadataPlugin subclasses can inherit (if MetadataRead is listed first in the ISA inheritance list) and which will then override the one defined in BasePlugin. For now committing MARC, ISIS and OAIPlugins which now additionally inherit from MetadataRead. Other metadataPlugins also need to be committed.
