#   Name:           add-telmetrywizard.ps1
#   Author:         Tyler Hughes (RandomlyKnighted)
#   Purpose:        This script recursively goes through all VSTemplate files located in the SideWaffle project adding a Wizard
#                   to each template. After implementation the wizard when used will use Google Analytics to help keep track of
#                   what templates are most commonly used.
