*class*to hold Moriarty's method with its various function pieces.Steffan: Uses the Python

`re`

regular expression module for some of the parsing, and pattern matching using`re`

is something you should definitely look into if you haven't already. Sets bounds on the SciPy minimizer to keep \(\phi\) phase values between 0 and 24hr.Sean: Includes some bonus scatter plotting of the fitted \(a\) and \(b\) parameters, showing that Moriarty's got other problems beside mis-estimating his phases \(\phi\).
