Substitute param with optional variable.
Fixed bug where certain parameters were being ignored when initialized.  This includes minDistance,
randomSP, and poolPct for FlatSpatialPooler. Flat Spatial Pooler Compatibility test
now runs fine without converting SP's on every iteration.

Added random seed logging in compatibility tests.

Refactored some of the test helper routines to a common support file.

Removed unused call to calculateOverlapPct
