    modified:   FittingTools.py
    Lots of changes:
     * correct handling of errors (with regards to Chi^2 tests)
     * When using scipy.optimize.leastsq, use the covariance matrix to set
       errorbars on the fitted parameters
       Still need to work out covariance calculations for other algorithms
