Created from a previous PR:

          Looks good. This covers most.. We may need to handle dashes in library names and any dot notation for namespace in the future.

ResourceFileName does not allow the name of the resource (e.g. Library or Measure) to have hypens '-' or underscores '_'. The underscores are explicitly prohibited as per specification for CQL Library Names, but the hypens are not.

This creates a problem, how to distinguish the parts in a Resource file name which could be either two or three parts where: xxx-yyy or yyy-zzz is xxx is the resource type (e.g. Library or Measure, etc), yyy is the name of the resource and zzz the version. It would be impossible to parse cases such as:

• Library-Common-1.0.0 (is Library-Common the library name, or just Common and the type is specified?)

Currently the NCQA cql files contain underscores, so they are invalid and should be renamed as part of this PR.
