//! The OpMarkupMouse class inserts a 2D rectange into a markup layer.  If a  markup layer is already active then the operator will use that layer otherwise the operator will create a new, unamed layer.
/*! 
  HOpMarkupMouse implements three mouse event methods defined on the base class and maps the event information
  to operator routines. This operation consists of the following steps:
  <ol>
  <li>Left Button Down:				register corner of rectangle
  <li>Left Button Down and Drag:	create an appropriately sized rectangle in the contruction layer
  <li>Left Button Up:				depending on existence of an active markup layer it either opens the existing or creates a new markup layer and inserts appropraitely sized rectangle into it
  </ol>
  More Detailed Description: see event methods
