To eliminate the number of parts problem I rewrote a section of the ODC master as simple c code. Functionality and channel names stayed the same. The parts count dropped from 3549 to 536.
The function that now does most of the work is MASKING_MATRIX in ODC_MASKING_MATRIX.c.

I also added a hook to include IPS error checking to that c-function.
