Work to speed up Connect_4. This is not done yet.

It should still work, though.
Added parallel_map to ADEUtils. This function might not work yet.
Removed some verbosity from randc.cpp.

This was done primarily so that any speed comparisons between fast and slow sqrts were not dominated by the
speed it takes to the output.
Better moment computation in moment_tests.

2 changes:
- moment_tests.do_line() now computs based on 10/90 cdf window, to be consistant with data

- new function, new_moments(), recomputes the data moments based on a window defined by a cross-correlated model
