// CLASS:    MFnArrayAttrsData
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MFnArrayAttrsData)
//
// MFnArrayAttrsData allows the creation and manipulation of MVectorArray and
// MDoubleArray data objects for use in the dependency graph.  
//
// If a user written dependency node either accepts or produces MVectorArrays,
// then this class is used to extract or create the data that comes from or
// goes to other dependency graph nodes.  The MDataHandle::type method will
// return kVectorArray when data of this type is present.  To access it, the
// MDataHandle::data method is used to get an MObject for the data and this 
// should then be used to initialize an instance of MFnArrayAttrsData.
