def python.uq.operations.forcePositivity.operationMakePositiveFast.OperationMakePositiveFast.coarsening	(		self,
			grid,
			alpha,
			newGridPoints,
			tol = 1e-14
	)

Removes all unnecessary grid points. A grid point is defined as
unnecessary if it is a leaf node and its hierarchical coefficient is
negative. This is applied just for the newly added points.
@param grid: Grid
@param alpha: numpy array hierarchical coefficients
