Interactive species and model plots

Russell Dinnage has just added a really cool feature: interactive plotting of enmtools.species and enmtools.model objects.  Here's a species:

And here's a model:

The maps are zoom-able and pan-able, and draw very quickly.  Source maps are downloaded from the internet on the fly, though, which means you do need an internet connection to use these functions.

The functions in question are "interactive.plot.enmtools.species" and "interactive.plot.enmtools.model", respectively.  All are now implemented on the master branch of ENMTools on GitHub.
