Robust Association Testing via Resampling

This is an attempt to test if two ECDF are independent

This was originally an attempt at trying to test if two ECDFs are independent through resampling.

The code resamples to get empirical conditional distributions, and then conducts a Kolmogorov-smirnov test to see if the conditional is the same as the unconditional. The median of (1 - p_values) is returned. This could easily be generalized to higher dimensions.
