OVERVIEW
1. Initiates connections to element and vmware
2. Asks user for the volume name of the datastore it will clone
3. Lists snapshots associated to the volume
4. Asks for user input of the snapshot to use for the clone
5. Creates clone of the snapshot
6. Presents clone to vmware and resignatures it as a datastore to recover vms
