Creates a linear (usually affine) transform which will map approximatively the given source points to the given target points.
Algorithms in this package use a least squares estimation method. The matching parameters are estimated by minimizing the sum of the squared distances between the given points and the fitted points (i.e. the points calculated using the transform). Note that "distance" here is not necessarily the Euclidian distance or a geodesic distance. It may be an approximation of Euclidian distance for implementation convenience.
