setCustomCommands

protected void setCustomCommands (RegexTrie<Runnable> trie, 
                 genericHelp, 
                 commandHelp)

A customization point that subclasses can use to alter which commands are available in the console.

Implementations should modify the genericHelp and commandHelp variables to document what functionality they may have added, modified, or removed.

Parameters
trie RegexTrie: The RegexTrie to add the commands to
genericHelp : A ERROR(/List) of lines to print when the user runs the "help" command with no arguments.
commandHelp : A ERROR(/Map) containing documentation for any new commands that may have been added. The key is a regular expression to use as a key for RegexTrie. The value should be a String containing the help text to print for that command.
