// .NAME vtkKWStateMachineDOTWriter - a state machine DOT writer.
// .SECTION Description
// This class is a state machine writer for the DOT format, based on the
// reference document: http://www.graphviz.org/Documentation/dotguide.pdf
// The resulting file can be rendered using dot:
//   dot -T png -o foo.png foo.txt
// It can also be used directly from a Wiki page if your MediaWiki supports
// the GraphViz extension (http://meta.wikimedia.org/wiki/GraphViz).
// A state machine is defined by a set of states, a set of inputs and a
// transition matrix that defines for each pair of (state,input) what is
// the next state to assume.
// .SECTION Thanks

// Computing (NAMIC), funded by the National Institutes of Health
// through the NIH Roadmap for Medical Research, Grant U54 EB005149.
