wumpus

Copperbox revision 1357.

I've added new examples to wumpus-core and wumpus-extra.

The new example in wumpus-core is a simple drawing using frameMulti. I was thinking frameMulti might generate bad PostScript (extraneous concat operations), but that doesn't seem to be the case, so I won't have to optimize wumpus-core like I was expecting to.

The new example in wumpus-extra uses the Path combinators from AffineTestBase.hs. I'm developing a module in Wumpus.Extra for paths, but a monadic formulation of the combinators looks to have advantages over the original one.
