Class to perform a Procrustes Analysis

Procrustes analysis is a form of statistical shape analysis used to analyze the distribution of a set of shapes. It allows to compare shapes (datasets) that have different rotations, scales and positions. It defines a measure called Procrustes distance that is an image of how different the shapes are.
