.SYNOPSIS
Returns an Object of SnapShot Data for specified VMs
.DESCRIPTION
Returns an object of VM, SnapName, Description, SizeGB, UserName, Created, and File of a snapshot.
Snapshot input must be piped from Get-SnapShot. See Examples.
Note: Time occassionally skews a few seconds between VIevent (log) and Snapshot (actual) info.
Ergo, this advanced function creates an 11 second window to correlate log information with actual information.
Snapshots taken on the same VM within 10 seconds of each other may produce innaccurate results. Optionally,
the 11 second window can be adjusted from 0 to 61 seconds by using the PreSeconds and PostSeconds parameters.
.PARAMETER Name
Pipe the Snapshot object. See Examples.
.PARAMETER PreSeconds
Number of seconds to capture VIEvents, before the SnapShot. Default value is 5.
.PARAMETER PostSeconds

Returns total size of VM on a Data Store.
.DESCRIPTION
Returns an object of total Datastore Consumption of a VM on a DataStore.
Includes all files: .log, .vmx, .vswp, .vmdk, etc. in the computation. Excludes ".rdmp" files (RDMs).
Note that a thin provisioned disk may reflect less disk space than is actually provisioned.
Default output is a hostname with total size. Accepts PipeLine input from Get-VM or CSV file.
Use the -full parameter to include all file names and thier values as an embedded object.
Optimally used with Get-VM, returning information into an object. See Example 4.
.PARAMETER vm
Mandatory. Enter vm name(s), use a variable, or pipe data in.
.PARAMETER full
Optional. Use to return all file names as an embedded object, along with the regular output.
.EXAMPLE
Displays VM name and total size:
Get-VMTotalSize -VM MyVm01
.EXAMPLE
Displays VM name and total size along with each file name and values:
Get-VMTotalSize -VM MyVm02 -full
.EXAMPLE
Displays VM names and total sizes via pipe from Get-VM:
Get-Vm MyVm* | Get-VMTotalSize

Sets Path Selection Policy for DataStores
.DESCRIPTION
Sets Path Selection Policy to either Most Recently Used, Fixed, or Round Robin. Does not attempt if the requested policy is already set.
Produces an object of DataStore, PathSelectionPolicy, HostName, Device, SetPathStatus, WorkingPaths, and CapacityGB for all requested DataStores.
Will check / set against every VMHost that has the DataStore Mounted. Will return pipeline error if a non-VMFS DataStore is piped in.
