function Set-Environment

.SYNOPSIS

Brings the CMD SET command back to PowerShell.

.DESCRIPTION

PowerShell has a powerfull way to set environment variables, but many of us 

have the DOS SET command burned into our fingers. This function keeps us

productive. :) 

Full credit to Wes Haggard at http://weblogs.asp.net/whaggard for this gem. 

To replace the default set alias with the one provided by WintellectPowerShell, 

execute the following command before importing the this module.

Remove-Item alias:set -Force -ErrorAction SilentlyContinue

.PARAMETER Var

The environment variable in SET format, "var=value". If you want to clear an 

environment variable, use "var=". If no parameter is specified, this will dump

all environment variables currently defined.
