PURPOSE:	Count AD Files Size and Objects
AUTHOR:		Axel Limousin
VERSION:	1.0
DATE:		03/01/2013
SYNTAX:		Get-ADCount <OutFormat> <DomainNC> <Scope>
EXAMPLE:	Get-ADCount Host
			Get-ADCount Host "DC=mydom,DC=com" Files
THANKS:		Technet
			Sean Metcalf, Bryan Sweeney, Alex Verboon, PScottC, jrv,
			Cédric Bigini, Olivier de Lagarde Montlezun, Freddy Elmaleh
COMMENTS:	Enhancements in next releases :
			- OutputFormat: ConvertTo-HTML
			- Count: DHCP, DNS, Bridgeheads, RODC, GC, GPLinks, DFS,
			check GC for DomainObjects of all Domains in Forest
			- Values comparison to highlight potential issues
