Detailed Description

Manage keywords for libdap. These are passed in to the library using the constraint expression - in fact they are an extension of the CE and this class implements the parsing needed to remove them from the CE so that the ConstraintExpression evaluator can parse it (because the keywords are not identifiers in the DDS, they will cause a parse error.

Note

If pointers are added to this code, modify DDS so copying still works!

The keywords are used to specify the DAP version(s) that the client can understand.

Keywords are parsed and used by the BES in Hyrax - libdap never makes calls to these methods.
