PowerCLI to check cross-connect active path correct for VPLEX

Usually hosts set their active path correctly from the disk nearest to the host, but sometimes they need help.  This script will email any paths on any hosts that are wrong.

Assumptions are that you have Site1 and Site2 in the hostnames.  PowerPath is the default path selection method, and it reports CL1 for cluster1 and CL2 for cluster2.   Hostname pattern is near script (I couldn't get it passed as a variable, let me know if you see how to fix that for us all).
