-- |Numerically solve convex lagrange multiplier problems with conjugate gradient descent. 
--  
--  Here is an example from the Wikipedia page on Lagrange multipliers.
--  Maximize f(x, y) = x + y, subject to the constraint x^2 + y^2 = 1 
--  
--  >>> solve 0.00001 (\[x, y] -> x + y) [\[x, y] -> x^2 + y^2 <=> 1] 2
--  Right ([0.707,0.707], [-0.707])
--  
--  The first elements of the result pair are the arguments for the objective function at the minimum. 
--  The second elements are the lagrange multipliers.
