Title: Revised algorithm to no longer be affected by floating point precision

Given the floating point issues in #15 and #16, I tried to revise how the algorithm works for exact elliptical aperture photometry, in order to no longer be affected so much by floating point accuracy (e.g. 1e-17 vs 0, etc.). Let's see if this passes on Travis.
