Remove depdency on Text::Balanced until I can make the logic work; regexen work nicely for now.
Removed option for null alias ("foo ="), leaving PHONY as a placeholder. This leaves the schedules a bit more obvious and less prone to dropout errors.
POD and comment updates. POD is still behind development but less so.
Basic interface for prepare/execute seems stable. A few more methods may be broken out but the top-level calls should remian stable.
test.pl needs to be updated with more complete tests for handling of perl blocks, restart and noabort.
