This file contains the VInstaller class which is used as the base class for VWP Module installers.
This system is used for installing Applications, Plugins, and Themes.
Note: This system includes modal features such as prompting a user. Modal features should not be used as not all installer applications will implement modal capability. Modal installers also make automated application deployment nearly impossible. Until these issues are resolved modal features may not be fully implemented.
