Get Matrix Parameter from current path segment

The @MatrixParam annotation will only detect matrix parameters when they are the
last thing in the URL. For example:

.../X;a=b will work

but .../X;a=b/ will not work

and .../X;a=b/Y/ will not work

Paul's suggestion to address this would be:

1) The ability to get the current path segment or segments associated with the
resource; and

2) a qualifier on @MatrixParam to declare that the matrix parameter is
associated with the current path segment
(or the last path segment in the current set).
