// <summary>
//
// This class encapsulates an enum with values corresponding to the various
// data components accessible via a VisBuffer.  Its current usage is to
// specify the VisBuffer components to be prefetched when asynchronous I/O
// is in use or to specify the VisBuffer components that have been modified
// when a Visibility Processing Framework bucket-brigade is operating on
// a VisBuffer.  This implementation should be replaced by a C++11 when
// the standard matures a bit.
