  * Add preliminary support for "wrapping" rather than transforming a module.
  This is incomplete, but basically the idea is to strip the module down
  to reveal just its interface, then add the minimal amount of boilerplate
  around that, to convert datatypes.  Thus, at runtime the original
  untransformed code will be executed, with a tiny layer to make it
  interact with fully traced code.
  
  Eventually, this will permit libraries to be sucked into Hat with
  greater ease.  There is still a lot to be done before it works however.

    M ./src/hattrans/Flags.hs +3
    M ./src/hattrans/HatTrans.hs -3 +10
    M ./src/hattrans/Makefile -1 +1
    A ./src/hattrans/Wrapper.hs
