 * ChimeraX 0.6 performance

+ - Looking up bfactor (1 million times):
+   - ChimeraX:
+     - ctypes: 1.38s
+     - custom library with property wrapping: 0.5s
+     - custom library with no wrapping: 0.185s
+     - random floating point attribute in Python: 0.072s
+   - Chimera 1:
+     - access bfactor via wrappy2: 0.062s
+ - Options:
+   - wrappy3 (does not understand numpy arrays)
+   - Cython
+ - Collect data
+   - Port custom library code to Chimera 1 and get timing.  Is it 3x slower due to argument parsing?
+   - Write custom library in Cython and compare against ctypes timing.
 * ChimeraX 0.6 APIs
  * Release APIs used in tutorials
