.SYNOPSIS
Chocolatey Wrapper

.DESCRIPTION
Wrapper arround the Chocolatey (Chocolatey.org) package wrapper system.

.NOTES

This script will read in a list of chocolatey packages from the MDT Chocolatey variable 
and install each package locally.

The Chocolatey scripts are kept in the c:\minint folder so they are not added to any images.
Because of this, be aware of any "Portable" applications that are installed under c:\minint.

CustomSettings.ini example:

[Settings]
Priority=Default
Properties=Chocolatey

[Default]
...
Chocolatey001=WindowsADK
Chocolatey002=AdobeReader
Chocolatey003=vcredist2010
