This commit separates the smoothness indicator and weight calculations
for 5th order WENO methods into different subroutines. This allows
modification of only the weight factor calculations for different WENO methods.
It extends the 5th order methods to include WENO5-JS, WENO5-Z+, WENO5-ZC,
WENO5-ZC+, WENO5-Z+M, and WENO5-AT.
