orthoHelper is just a chare array to host the 2nd multiply of the S->T method. It should be mapped adjacent to ortho such that ortho(x,y) and orthoHelper(x,y) are on different processors which are only one away. This assumes that ortho itself is mapped with a stride greater than 1. Orthohelper should only be used if numProcs >= 2 x numOrtho chares, otherwise we expect the parallelism gains would be lost to communication overhead.

OrthoHelper is triggered by being given the result of multiply 1 by Ortho. It then computes multiply 2 and returns it to the ortho chares who sent it the multiply 1 input. This is a simple point to point communication ortho(x,y) <-> orthoHelper(x,y). Ortho then proceeds as normal through the S->T process.
