SECEditCommand Class

class SECEditCommand: public MvcCommand, public SECEditLineColPair

This class derives from SECEditLineColPair and so has a starting and an ending Line/Col. When creating an Insert command, specify the starting line/column indices and the text. When the command executes, it will populate the ending line/column indices (needed to do a delete) When creating a delete command, specify the starting and ending indices. When the command executes, it will store the text to restore.

Note that you can directly call the SECEdit functions Insert and ClearTextBlock and a command will be created automatically and put on the undo stack.
