Detailed Description

Implements the main kernel debugger. This class interfaces with the machine abstraction to provide trap and breakpoint services. It exposes a set of commands, which are accessed by the user through a command-line interface defined by a concretion of the abstract class DebuggerIO. The kernel can also write entries to the (debug) system log by calling operator<< directly.
