Simple implementation of the DeltaBlue multi-way constraint solving algorithm.
Constraint solvers, generally, are good for solving problems which fit the description of "when this value changes, update these other values." Think Rake, but for your program's data instead of files. Rake is actually a constraint solver itself: when a file is updated, it knows which other files to update and the how to update them. Similarly, when a DeltaRed "variable" changes, DeltaRed knows which other variables to update and how to update them.
