Renamed BuddyNode to BlockNode since it is now used by both allocators.

Moved some code around in an attempt to organize it more top-down.

Moved the report printing into the Simulation base class.  Print the

report printing if only one previous report was printed.

1000*1000.  This makes it easier to specify cache sizes for the buddy
system that don't have to be rounded up to the next power of two.  It

- Support reading gzipped files.  This is triggered automatically when
  the filename ends in .gz.  Also support reading from stdin (pass '-'
  as filename).

- Widen the FLIPS column by one to match the EVICTS column width of
  the LRU simulation.

- Support simulating alternative caching strategies.  For now, only
  LRU is supported, triggered by the -l option.

- Change the Simulation base class to store the cachelimit argument.
