This class initializes the W matrix of the AMF algorithm by averaging p randomly chosen columns of V.
In this case, p is a template parameter. H is then filled using a uniform distribution in the range [0, 1].
This simple initialization is the "random Acol initialization" found in the following paper:
columnsToAverage  The number of random columns to average for each column of W.
