Toy implementation of QRS surface metrics for extreme event prediction quality

Toy implementation of QRS surface metrics for extreme event prediction quality

Accompanying documentation has been submitted for publication.

Features:

two toy models: a bimodal distribution and a multivariate Gaussian distribution
two dynamical systems: the Majda-McLaughlin-Tabak model and the Kolmogorov Flow model
produces both pdf and QRS plots
outputs either analytic results, or simulates sampled results
