Detailed Description

This component allows a text client to browse the peers of a peer RTT::TaskContext and execute commands. If your console does not support colors or you want a different prompt, the member variables which control these 'escape sequences' are public and may be changed. The TaskBrowser is most commonly used with its loop() method, but prior to/after calling loop(), you can invoke some other commands, to control what is displayed or to execute a fixed set of commands prior to showng the prompt.
