Remove Maxwell3D Zero Initialization Calls

Browse Source 
A lot of calls in Maxwell3D register initialization ended up setting the register to 0 which should be implicit behavior and most calls would be eliminated by the redundancy check which had to be manually disabled. It was determined to be better to move this responsibility to the called function to initialize to state equivalent to the corresponding register being 0. All initialization calls with the argument as 0 have been removed now due to this, it was the vast majority of calls.
