// This function is called by the DisplayNode object
// This function needs to be defined outside the SCL libraries.  It needs to do

// 1) unmap the StepEntityEditor window if it is mapped.
// 2) delete the StepEntityEditor window
// To see an example of this function used with the Data Probe look in
// ../clprobe-ui/StepEntEditor.cc  Look at DeleteSEE() and ~StepEntityEditor().
