Numerical integration for laplace coefficients partially implemented
indirect terms added to DFCoefficients
Added functions to compute arrays of laplace coefficients.
Changed syntax in fitnessNew to account for the now-one-dimensional
arrays.  Still need to find a way to get the period ratio into
fitnessNEW in order to do calculations.
began overhaul of fitness to object-based version
=still working on fitness
working version with exact laplace coefficients
working version with exact laplace coefficients
function return values changed to numpy arrays for faster evaluation
initilization eccentricities set to gaussian around 0
Added plotting functions.  Allow for masses fitted parameters
