//! \brief Class for working with Maya's Evaluation Manager. 
/*!
  The Evaluation Manager is used to evaluate the scene without dirty
  propagation. Its evaluation graph capabilities decouples the data model 
  and evaluation.

  The Evaluation Manager can execute graph evaluation in serial or parallel.
  Parallel execution uses a scheduling graph to provide parallelized
  computation of depend nodes.

  Unless specified, the methods in this class are threadsafe and can be
  performed safely from worker threads.
