Calcualte least square cross validation bandwidth
Function to estimate 2 dimensional least square cross validation for kernel density estimation

Powell (1996), but uses a binned algorithm. If
"global" the global minimum is
returned, else the local minimum with the largest
candidate bandwidth is returned.
