Recursively merge two or more hashes, simply
HashMergeSimple will recursively merge two or more hashes and return the result as a new hash reference. The merge function will descend and merge hashes that exist under the same node in both the left and right hash, but doesn’t attempt to combine arrays, objects, scalars, or anything else. The rightmost hash also takes precedence, replacing whatever was in the left hash if a conflict occurs.
This code was pretty much taken straight from CatalystUtils, and modified to handle more than 2 hashes at the same time.
