Commissioning tests

[pllim]

Implements most of #12 (if not all).

Note: Technically Travis CI could be modify to run this, but it is not advisable. This is meant to be run locally by developers and users.

Results are at http://ssb.stsci.edu/stsynphot/report.html (tested synphot/stsynphot 0.1b1 against ASTROLIB pysynphot 0.9.8.5)
