- Added a parameter to the PCA computation that returns the first and second
...
eigenvalues of the covariance matrix associated with the cluster.
- Compared results of testing the ratio of eigenvalues as a measurement of
'linearity' for the different shapes, and output statistics.
- Added a #define that controls whether or not we do shape estimation using
quantized AABB error or eigenvalue ratios. The former seems to be better.

Fix a few issues and make sure that when we write out to a file, only the intended values are reported. We still have to fix the accumulated stat reporting and make it thread-safe.
