ellipsoidTransform

Takes a vector <code>x</code> and transforms the points onto the same geometry of
a normalised ellipse given by the inverse of the covariance matrix
<code>SigSqrt</code> and the location <code>mu</code>.

Fits bi-variate ellipses to stable isotope data using Bayesian
inference with the aim being to describe and compare their isotopic
niche.
