**What it does**

Creates a shape composed of any number of selected shapes where the composition is based on a mathematical
expression consisting of **+**, **-** and ***** operations.  The **+** results in a union of shapes, the
**-** operator removes a shape and the ***** operator results in an intersection of shapes.

For example, if the **Composition expression** is **A + B - C - D**, selecting 4 shapes from your history
and associating each shape with a variable from the expression will result in a shape composed of the shapes
associated with A and B, but eliminating the shapes associated with C and D.
