David Wang 7e908457a2 Add equality constraint. 
This is a very simple equality constraint.  It only assigns a variable
when all other variables in the equation have been assigned.  Possible
improvements:

- We can find the min and max range by considering the coefficients
  and the max and min values of the other variables in the equation.

- When there are only 2 variables remaining, we can eliminate the
  incompatible candidates and then substitute one variable for the
  other in other constraints.
