 The picture below shows the computational graph for the expression `φ=cos(v1)v2` and the compile-time representation as object with `su2double` being the general datatype used throughout SU2.

 activity tracking is relatively easy to accomplish since every variable stores an index along with its value. A
 zero index represents passive variables while a non-zero index identifies active variables. This index will be
