add a more convenient interface for constraintw #8

Constraints should be usable in a method more like PuLP-OR:

solver += -4 * x + y

Where x and y are variables.

# Adding constraints:
solver += x + y <= 2
solver += 3*x - 4*y >= 1
for a, b, c in foo:
    solver += x/a + b*y == c

# Solving with an objective:
solver.minimize(objective=c*x + y/d)

# Remove constraints:
solver -= constraint
solver -= x + y <= 2

If possible, maybe we can do this too: 

solver += 1 <= 3x + y <= 2
