Oops, forgot to add this to previous commit
Snapshot of a first-draft Filerator module

(Sadly it does not work)
This filerator now does work -- using a module in an iterator broke it apparently

Not sure why, but somehow the use of a helper module to get my externs
didn't work in the original filerator
SImplified versions of tests that now use the Filerator module

(Oh, and they also move 'sorter()' out to the Sort module)
Add support for octal literals in the compiler.

Additionally, adds three tests: one for the most common case, one that include

rejected.

Add a feature request future for octal formatted printing.

This looks non-trivial and shouldn't hold up octal abilities, at least in the
use case we desire it for.
