Release Name: 0.1.9 December 2016 checkpoint release

Notes:


Changes:
Added code to allow runtime memory profiling if memory_profile library is present.
Extensive casting of variables to lower memory footprint and allow future optimizations.
Added explicit garbage collection to reduce memory usage.
Added optional single precision calculation mode to lower memory footprint.
Added a second script, "rapidtide2x" where I can distribute and test new features without breaking the main code branch.
Did some speed optimizations in findmaxlag, including faster gaussian fitting and new MUCH faster parabolic fitting (still experimental).
Minor bug fixes, code reorganization and cleanup.
