Basic .acsv reading and fiducial-point creating program.
Add git ignore file and clean up the code a bit.
Made the point dictionary ordered to clean up output and facilitate later calculations.
Minor refactoring of names.  Also added a bit of a trial of array math
to get a distance vector between two points.
Added new vector math - it works!  Woo!

Also split out debug utilities and vector math into their own files for
clean coding.
Update gitignore.
Some additional refactoring including unit tests for VectorMath and a
rename for pelvic_points.
Refactored code again - added MRML parsing capability and broke out
directory searching capability and fiducial classes into their own
files.
Minor tweaks.
Minor changes to make the debug printing correct.
Add graphing capabilities and a (nascent) pelvic point reasoning module.
Continuing cleanup.  Color coding where RGB=XYZ.
Minor cleanup and fix setdebuglevel.
P->IS distances working.
More code cleanup.
Get rid of some compiled .pyc files that snuck in.
Get rid of some compiled .pyc files that snuck in.
Added a few corrections to coloration (i.e. ignore points *on* the reference line when trying to determine distance ranges).  Also, added a legend to the graph and fixes its axes.
Improve VectorMath by adding orthogonalize (cross product) function.  Add some new unit tests as well.
Simplify and cleanup.  Also add recenter and reorient functions for transformations.
