Given an RDD or grid-mapped values (with keys of the form (row, col)), compute a "partial-sum RDD", where each element's value is replaced with the sum of the values of all elements with keys from higher (or equal) rows and columns.

V
value type.
rdd
input RDD.
m
implicit Monoid exposing "addition" and identity for type V.
returns
a tuple consisting of the input RDD partitioned into a grid by its key (row, col) tuples, a "partial-sum" RDD as described above, and the maximum row- and column- values found.
