Indirect Functoids

This is perhaps the most Boost-redundant feature of the library.  FC++
indirect functoids do almost the same thing as boost::function objects.
The differences:
 - indirect functoids are imbued with "full functoid" features
 - indirect functoids don't work with non-const reference parameters,
   whereas boost::function object do
 - indirect functoids can't be "null", whereas boost::function objects
   can

There is also an implementation dependency that FC++ lazy lists rely on
indirect functoids in their implementation, but I think this dependency
could be removed (creating a dependency on boost::function instead).

If FC++ were accepted into Boost, my gut tells me that in the
long-term, indirect functoids would naturally disappear (by getting 
absorbed by boost::function).
