Create a my:carrot-invoke() function for MarkLogic

[evanlenz]

It would lazily compile the given Carrot module(s) to XSLT and then call xdmp:xslt-invoke(). Find a way to cache the compiled XSLT so that the function doesn't have to re-compile every time. Server field? Stored code in a database?

Oh yeah, first implement Carrot... we'll get there.
