/*
* Generate measures based on a selected calculation items already created.
*
* Author: Dan Meissner
*
* You must have created the calculation group items beforehand.
*
* This script will work on any calculation groups/items within the model, but is most useful
* and was conceived specifically for Time Intelligence Calc. Items.
*
* Once one or more measures are selected, running this script will pop up a dialog box that
* allows the user to select a Calculation Group and then select one or more Calculation Items
* from that group. The script will then make a single measure for each base measure && calc item
* combination. The new measures will maintain the format string of the original base measure
* and will be created in the same display folder as the original base measure.
