************************************************************************

This script takes in a given VMFS and finds all VMs that have VVol-based virtual disks. It also takes in a target VVol datastore.
The script then creates the requisite number of VVols for each VM with the correct sizes on that target VVol datastore.

Requires:
-VMware PowerCLI 6.5+
-Microsoft PowerShell 4+ is highly recommended
-FlashArray Purity 5.0+
-vCenter 6.5+
