// CLASS DESCRIPTION (MPxFieldNode)
|
|
//
|
|
// MPxFieldNode allows the creation and manipulation of dependency graph nodes
|
|
// representing fields. This is the top level of a hierarchy of field
|
|
// node function sets. It permits manipulation of the attributes common to
|
|
// all types of fields.
