Fixed data-output bugs and corrected language in docs about default density-grid window size.
1.3.8
Fixed the bug in `mating_radius=None` behavior, and folded genetic PCA-mapping function from the IBD/IBE demo into the main package as `mod.plot_genetic_PCA`.
1.3.7
Fixed a couple bugs with point-sampling behavior and non-neutral locus file writing behavior. Also incorporated a host of other small and overall inconsequential changes.
1.3.6
Fixed a latent bug that allowed trait-associated loci to have NaN effect sizes.
1.3.5
Fixed genome.py so that it throws a warning, not an error, if all mutation rates are 0 and there are 0 neutral loci in a model.
1.3.4
Tweaked genome.py, trying to make it possible to use L non-neutral loci in a genome of length L (i.e., to have no neutral loci remaining).
