.SYNOPSIS
Returns an Object of SnapShot Data for specified VMs
.DESCRIPTION
Returns an object of VM, SnapName, SnapDescription, SizeGB, File, UserName and CreatedTime of a snapshot.
Snapshot input must be piped from Get-SnapShot. See Examples. Auto-Generated SYNTAX (above) is not quite accurate.
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. Auto-Generated SYNTAX (above) is not quite accurate.
.PARAMETER PreSeconds
Number of seconds to capture VIEvents, before the SnapShot. Default value is 5.
.PARAMETER PostSeconds
Number of seconds to capture VIEvents, after the SnapShot. Default value is 5.
.INPUTS
VMWare SnapShot Object from Get-SnapShot
.OUTPUTS
PSCUSTOMOBJECT SupSkiFun.SnapShotData
.EXAMPLE
Obtain Snapshot Data from one VM:
Get-SnapShot -VM Guest01 | Get-SnapShotData
.EXAMPLE
Obtain Snapshot Data from multiple VMs, using the Get-SnapShotData alias, placing the object into a variable:
$MyVar = Get-Snapshot -VM *WEB* | gsd
.EXAMPLE
Obtain Snapshot Data from one VM, increasing the VIEvent window to 31 seconds by setting both the PreSeconds and PostSeconds parameters to 15:

.SYNOPSIS
Returns an object reflecting the status of Vsphere Clusters and VMHosts.
.DESCRIPTION
By default (i.e. with no parameters), returns an object of Name, Type, Overall Status and Config Status of
all Clusters and VMHosts. Specific Cluster(s) and/or VMHosts(s) can be specified with parameters.
See Parameters and Examples. Most common use is Example 4. Non-green statuses return error(s) within Config.
.PARAMETER Cluster
Optional. If defined, returns only the Cluster(s) specified. Can be combined with VMHost.
.PARAMETER VMHost
Optional. If defined, returns only the VMHost(s) specified. Can be combined with Cluster.
