Removed RootTools source.
Added RootShell source.
Removed dependency on RootTools, added dependency on RootShell.
Fixed code to account for RootShell, added note about the potentially improper use of RootShell.
The code will work fine, but ideally shell commands should either be done in a shell or commandWait should be removed and the callback methods should be used to continue the flow of execution.
