/*******************************
         Install Task
*******************************/

/*
   Install tasks

   For more notes

   * Runs automatically after npm update (hooks)
   * (NPM) Install - Will ask for where to put semantic (outside pm folder)
   * (NPM) Upgrade - Will look for semantic install, copy over files and update if new version
   * Standard installer runs asking for paths to site files etc
