// CLASS DESCRIPTION (MDataBlock)
//
// An MDataBlock provides storage for the data being received by or sent by
// the node. It is the data for the plugs and attributes of the node. The
// data block is only valid during the compute method of the depend node,
// and should not be stored.
//
// Access to the data in an MDataBlock is done using an MDataHandle or an
// MArrayDataHandle.
