Description

-Enable/disable terrain slope and azimuth angle inputs for subarrays based on track mode, backtrack, and shade mode for each subarray
-For documentation, rules are as follows:

1. Single axis tracking must be selected
2. At least one of backtracking enabled and shade mode set to Linear must be true.
   Otherwise terrain inputs are disabled as they do not impact results.
