Better error handling for parsers.
Checking for a non-empty list in expand-docs.
Factoring print-module-docs and print-module-binding-docs into (chibi doc).
Adding @help to (chibi repl) to lookup online docs.
Render parameter in print-module-[binding-]docs can be made #f for the default.
Generating lib docs in html format.
Handling raw numbers in sxml format.
Default test comparator should require same exactness.
Fixing exactness in square test.

Fixes issue #178.
Differentiating between analyze_app and the new analyze_list.
The latter is just for any list of ASTs to analyze, whereas the former

now returns true.
Adding procedure-docs and print-procedure-docs.
