示例1: build_basemap

"""
First try at a building of the basemap with a 'stere' projection
Must put in the values of the lower left corner and upper right corner (lon and lat)
Defaults to draw 8 meridians and parallels
Modified: Samuel LeBlanc, 2015-09-15, NASA Ames
- added profile keyword that contains the basemap profile dict for plotting the corners
- added programatic determination of basemap parallels and meridians
Modified: Samuel LeBlanc, 2016-07-17, Santa Cruz, CA
- added plotting of larger region, which is then resized, to have space to pan and zoom.
