// CLASS:    MFnData

//
// CLASS DESCRIPTION (MFnData)
// 
//   MFnData is the parent class for all dependency graph data function 
//   sets.  Conceptually, data objects are what flow through the connections
//   in the dependency graph.
//   
//   Each node in the dependency graph has a data block associated with it.
//   The data block holds the data objects for all of the node's attributes
//   (see MDataBlock).  The data block is only available during the compute
//   method of a node.  A data handle (MDataHandle) can be created to access
//   a particular attribute's data inside of the data block.
//   
//   Once a data handle is obtained, it is possible to get the data object
//   from it.  This is only necessary for heavier data structures such as
//   geometry or strings.  Simple numeric data can be manipulated straight
//   through the data handle.
