.SYNOPSIS
	Produce a simple HTML report of all files in a folder, who the owner is
	and when the file was last written.
.DESCRIPTION
	Produce a simple HTML report of all files in a folder, who the owner is
	and when the file was last written.  You can specify if you want all sub-
	folders included in the report and also narrow the report to specific
	extensions if you want.

	Make sure to edit the $ReportPath in the parameters section to match your
	environment (if desired).

	**CAUTION** The bigger the directory structure the longer this script will
	run.  Be patient!

	place the HTML report in the s:\it folder.
.EXAMPLE
	.\Get-FileOwner.ps1 -path s:\accounting -SubFolders $false
	Will create a report of all files in the s:\accounting folder only and place
	the report in the default location, c:\utils.
