- This is a large commit, as all the changes are centered around the elimination
of CLI.
- CLI is no longer compiled.
- Context no longer maintains CLI + CLI2.
- Filter now walks the parse tree and sends to Eval a
std::vector <std::pair <std::string, Lexer::Type>> containing only args tagged
with FILTER.
- Filter more efficiently sets/unsets Eval::debug, by doing it less often.
- The filterExpr.length() check is no longer meaningful, and instead the size of
the std::vector above is used.
- Filter::pendingOnly performs better analysis.
- Filter::safety makes use of the std::vector size also.
- Task::modify makes use of 'canonical' rather than 'name', which is a policy
change, not a fix.
- Implemented info report.
- Removed odd Subst and Sequence objects from Task - are they just
vestigial limbs, or did I add them for a good reason? They are
gone now.
- Added Filter::applySequence to replace old filterSequence.
- Removed obsolete report.cpp filter function.
