You're moving. And that means a whole bunch of boxes need to be moved from the
old place to the new one. You've got a pickup truck to do the moving, but it can
only hold one vertical level of boxes. The boxes need to be padded with one unit
worth of foam on each side that's facing another box.

The goal is to minimize the amount of trips you have to do to move all the
boxes.

The solver program should take two lines of input, first one containing the
trunk dimensions (e.g. 10x20), and the second one containing all the box
dimensions, separated by spaces (e.g. 1x3 4x8 3x7 9x4 10x14.)

The output of the solver should be ascii art of the trunk packings, with each
trunkful separated by an empty line.

	Example:
	$ ruby solver.rb
	10x20
	1x3 4x8 3x7 9x4 10x14
