Assigns fibre orientation vectors for papillary muscle structures. Vectors are assigned to be parallel to the direction of the axis of the muscle. To do this we use the "Structure Tensor" method.

Smoothes the structure tensor components for each papillary element by looping over all other papillary elements, calculating distance geometric distance between the two elements; if it is within a certain limit, include this in the Gaussian kernel
Here mStructureTensors[i] is the 'rough' tensor for each element and mSmoothedStructureTensors[i] is the smoothed tensor for each element
