Reconfiguring paths to be portable/mac-friendly.
Disabled the code that makes glued two-panel plots. Now all are onepanel.

Some minor fixes otherwise: removing parameters that aren't relevant / aren't implemented yet in the jjh function.
Making sure the date_offset is set correctly -- to the Orion startdate.

The code this is cloned from didn't have it because it had plot3.graded_lc(abridged=True) set, which auto-resets the default date_offset to the Orion startdate.

I screwed this up the first time, and amended it to the correct Orion startdate.
