// Class: CAMCViewToolbars
//
// Synopsis: This object maintains data for the toolbars of a CAMCView.
// When its view is active it adds the toolbar buttons to the
// main toolbar UI and handles any of the UI messages.
//
// Desc: This object is created and destroyed by the view. It
// provides following services.
// 1. ability to create/destroy toolbars for this view.
// 2. to manipulate single toolbar. It maintains an array of
// toolbuttons from all snapins including std toolbar.
// 3. to observe the view for activation & de-activation.
// When the view becomes active it adds the buttons & handles
// any button click & tooltip notifications.
// 4. It maintains a single imagelist for all the toolbars for
// this object. To get image index for a tool button it maintains
// a map of CToolbarNotify* (the snapin toolbar) and imagelist
// information like start index & number of images for this CToolbarNotify*
// in that imagelist.
//
// It also provides unique command id for each button (as there is only
// one toolbar UI which needs unique command id for each button from
// different snapin).

* There is only one imagelist for this object. All the snapin toolbars

* So when we add bitmaps for a toolbar we need to know where it starts
* in the imagelist and how many are added.
* So we maintain a data struct between toolbar (CToolbarNotify*) and an
* object (MMCToolbarImages) containing start index & number of images.
*
* A snapin may add bitmaps multiple times for single toolbar. Each bitmap
* is added at different start index.
* So the data struct is a multi-map between toolbar (CToolbarNotify*)
* and MMCToolbarImages.
*
* Assume a snapin adds 3 bitmaps initialy & then 4. Then while adding
* buttons it will specify bitmap index as 5.
*
* The first MMCToolbarImages has cCount = 3, iStartWRTSnapin = 0, thus
* images from 0 (iStartWRTSnapin) to 3 (iStartWRTSnapin + cCount) with respect
* to snapin.
* The second MMCToolbarImages has cCount = 4, iStartWRTSnapin = 3, thus
* images from 3(iStartWRTSnapin) to 7(iStartWRTSnapin + cCount) wrt snapin.
* So MMCToolbarImages has iStartWRTSnapin member in addition.
