LoadDeriscope is a vba function that takes 0arguments
It returns TRUE on success and FALSE on failure.
This function enables Deriscope by loading the Deriscope dlls - if not already loaded - without showing any tutorials.
It simulates the effect of clicking on the Load Deriscope ribbon button

It is needed if the vba routine is supposed to run regardless of the enabled status of Deriscope at the time when the routine is called.
