enforce that the address range of devices falls within the address range of the bus. Turned out that the CPU tests instantiate memory with the last parameter as memory size, not end address (fixed now). Also make sure that the address lookup array takes the offset caused by non-zero starting addresses into account.

Execution Trace Log
...
Introduces an execution trace window that will keep track of the most
recent 10000 execution steps. I'm not entirely happy with the

- Major overhaul of the Simulator control class (where 'main' lives).
...
- Removed the CommandParser class entirely, as the weird dependency between
Simulator and CommandParser never made me comfortable.
- Added a Command inner class to Simulator that handles some of the
command line tokenizing.

- Continued refactoring of address decoding.
...
- Device read and write may now throw MemoryAccessException, and appropriate
throws clauses have been added throughout the code.
