// CLASS DESCRIPTION (MItSelectionList)
//
// Class for iterating over the items in an MSelection list.
// A filter can be specified so that only those items of interest on a selection
// list can be obtained.
// 
// If a filter is specified then the children of DAG selection items will be
// searched if the selection item does not match the filter.
// For example, if filter = MFn::kNurbsCurve and a transform is selected
// then the underlying shape for the transform will be in the iteration if it
// is a nurbs curve.
