// A CPartialAssemblyVersion is a class that wraps an inexact version
// specification.
//
// The initial implementation just assumes that it's basically an ASSEMBLY_VERSION,
// but that any of the fields may be "wildcarded".
//
// Future versions may allow for more interesting partial version specifications
// such as "major=5; minor=1; build=2103; revision >= 100". This is beyond the
// bounds of the initial implementation, but forms the basis for the public
// interface (parse, format, test match)
//
