+// CLASS DESCRIPTION (MFnAttribute)
+//
+//  MFnAttribute is the function set for dependency node attributes.  
+//
+//  An attribute of a dependency node describes a piece of data that belongs to 
+//  nodes of that type.  For example, a node that makes a sphere might have a 
+//  radius attribute.  A node's attributes describe connections sites on the
+//  node that can be used in the dependency graph.
+//
+//  Attributes typically belong to a class of nodes, rather than to an
+//  individual node.  For example, all sphere nodes have a radius.  Even though
+//  a single attribute may be shared by all nodes of a given type, each node
+//  will have  its own value for the attribute.
+//
+//  Attributes are heirarchical.  For example, the translate scale attribute
+//  of a transform has x, y, and z child attributes.
+//
