// CLASS:    MItInstancer

// *****************************************************************************
//
// CLASS DESCRIPTION (MItInstancer)
//
// Use the particle instancer node iterator to traverse all instancer nodes in 
// Maya's Dependency Graph, and optionally 
// 
// With filtering enabled, the iterator checks to see if the node is
// compatible with the type specified by the filter.  See MFn::Type for a
// list of all valid types.
// 
// Since MObjects may be compatible with more than one type (nodes are
// organised in a hierarchy) the MObject::hasFn() method can be used to
// further check for compatible types.
// 
// Any compatible Function Set can be attached to the retrieved object to
// query or or edit it.  Often you will want to use the dependency node
// function set (MFnDependencyNode), which is compatible with all
// dependency nodes, to perform queries on each node as the iterator
// Traverses the Dependency Graph.
