Fit signals found with some kind of light curve model #42

Suggestion from @peter-r-mccullough. Fitting with a Mandel & Agol model may be overkill, but we can use a trapezoidal model instead for fast convergence. I have an improved version of this model that I can share after the paper is accepted to ApJ; we could start out using the one from Carter et al. (2008).

Binned trapezoidal model paper has been accepted, so hopefully the code can be made available soon.

Remaining objectives:

  1. Add box vs. trapezoid as option.
  2. Use something based on fraction of BLS width as guess for tau.

Box vs. trapezoid is now a parameter file option. I am using 0.25 * T as a guess for tau, and this seems to work fairly well.
