in the middle of refactoring mplotqueries. this does not run currently.
refactor working except for overlays.
ongoing re-factoring. changed parser structure.

TODO: add default --plot option if none given. try sub-command parser again?
fixed small bug. don't assume there is always a filename.
restructuring complete. testing phase.
added some help text to group/label.
made parsing for datetime roughly 5x faster (bug that kept searching for date even if one was found already), and some minor improvements.
made the lines of event plots less transparent.
changed order of comparisons upon adding line to plot, making parsing 3x faster. ~200MB now take 15sec.
Merge branch 'master' into mpl-refactor
added range type bars to legend. Clicking on a bar now prints the first and last occurrence of that group.
