class SGDMonoid[Pos] extends Monoid[SGD[Pos]]

Basically a specific implementation of the RightFoldedMonoid gradient is the gradient of the function to be minimized To use this, you need to insert an initial weight SGDWeights before you start adding SGDPos objects. Otherwise you will just be doing list concatenation.
