This commit includes a new utility, the decomposer, which has
primarily been used to test the AST against found scheme code in
the wild (internet). Decomposer will time and test the lexing and
parsing of any document full of scheme.
This commit includes additional test cases and logical fixes for
issues found during the testing performed.
