Added determinant and inverse MX nodes
Redefined gradient(MX,MX) and gradient(SXMatrix,SXMatrix) to use SXMatrix::grad() and MX::grad(). These differ from trans(jacobian(.,.)) in sparsity pattern and when arguments are matrix valued.
Correction to 4eac2a25c80798ae8fcf2d9c793ed32e7aba34d5
Fixed hessian(SXMatrix) implementation exposed due to 74d4a09c9dc66020ad7ab1df6dca2d883d5265ec
Added inner product MX node
Added derivative propagation rules for InnerProd
Added evaluation for InnerProd
