Major overhaul of quadratures.  1-D quadratures have been abstracted out as base quadratures.  Separate polar and azimuth quadratures exist, where the former becomes a 1-D quadrature for transport.  Together, the two make up product quadratures via templates.  Doing it this way has shaved a few hundred lines of code while providing many possible quadratures (over 80), though many combinations are not desirable (and hence not instantiated).  The MOC-specific quadratures have been eliminated as a move from cyclic tracking is made.  The source is still there for when I get a chance to adapt it to give essentially cyclic-tracking results without doing it explicitly.
More changes to geometry.  Disabled old MOC stuff throughout.
New plotting utilities, including color maps
Several additions to the new geometry stuff.  Tracking in 2-D is lightly tested.
