> Function to fit an exponential decay (negarive beta) or positive beta without
> initial guessing
> Based on [https://stackoverflow.com/a/39436209/545346]
> Original source: Regressions et Equations integrales, Jean Jacquelin
> [https://www.scribd.com/doc/14674814/Regressions-et-equations-integrales]
> The class will allow for the usual variety of providing inputs of x and y.
> Once computed the instance can be queried for Amplitude, Beta, and Constant,
> defining a curve for y= Amplitude * exp(Beta * x) + Constant
