> The main purpose of this patch is to refactor the metadata parsing
> functionality into an extensible framework of MetadataExtractors. The
> MetadataExtractor interface defines the general capability of parsing a
> metadata source and adding (name,value) pairs into the CAS metadata
> container. The existing code for parsing THREDDS metadata catalogs has been
> moved from the DatasetCrawler class to a ThreddsMetadataExtractor that
> implements the aforementioned interface. Additionally, another
> implementation, DasMetadataExtractor, has been added to parse an Opendap DAS
> stream and capture the NetCDF global attributes (for now). Finally, an
> NcmlMetadataExtractor has been added as a stub implementation for future
> parsing of NcML documents.
> The patch also contains the following changes and additions:
> o The OODT profiles are assigned a UUID as identifier, since the THREDDS
> dataset ID is used as the resource identifier
> o The THREDDS catalogs are parsed to extract the CF standard names and
> variable long names, where found
