An introspection based predicate matching using a template object. Allows for partial match of two protocl Objects.

Parameters:
other the match pattern to test against. The match object has to be of the same type (class). Primitive types and non-sip fields that are non null are matched for equality. Null in any field matches anything. Some book-keeping fields are ignored when making the comparison.
Returns:
true if match succeeds false otherwise.
