 MODIFICATION HISTORY:
    2004/04, Written by Doug Loucks, Consultant for Lowell Observatory.
    (See cw_cpmgr.pro)
    Removed all remnants of compound-widget code; replaced with
 stand-alone code that is compatible with the new object-oriented version
 of itool.
    Modified the usage of the state-structure variable. A pointer to
 the state structure is stored in the object instance of this tool and
 this tool's object reference is stored in its top-level base.
    Modified the storage of the three variables pidx, pidxcum, and pidxall.
 Now, pointers to these are allocated and copies of the pointers are stored
 in the state structure and in the object instance, providing quick access
 from event handlers and from method routines.
    Modified the incoming argument. Now, it is the object reference of the
 host instance of itool, which is stored in this tool's object instance.

    2006/03/15 - DWL, Minor modifications to use the methods of the new
                   'itoolimage' object class that was added to the itool GUI.
                   See itoolimage__define.pro and itool__define.pro for
                   details.
    2006/5/22  - Peter L. Collins, Lowell Observatory
                   added processing for CCD readout noise ("rdnoise") in
                   the photometry parameters- specifically, in calls to
                   basphote.
