Add visualize.height_distribution

[k034b363]

Describe your changes
Our percentile-based plot height analysis function requires choosing an upper and lower percentile threshold to subtract for a plot-level height estimate. It would be helpful to be able to see some distributions of pixel values in individual plots in the DEM to help choose sensible cutoffs. This PR adds a sub-module called visualize and a function height_distribution that plots histograms for a random subset of plots in a provided shapefile.
