The MonotoneSolver class is the base class of the monotone framework. Given a lattice, an instruction graph, an initial state vector, and some other objects the monotone framework tries to propagate information from node to node of the instruction graph until no further information can be deduced from the current program state and the transforming instructions.

| <Lattice> | Type of the lattice the monotone framework is using. | |
| <LatticeElement> | Type of the elements of the lattice. | |

Run the actual code analysis.
Starting from the initial state vector, iterate the transformation until a fixpoint is reached.
Depending on your analysis, your transformations and the program you are analyzing, it is conceivable that this will iterate for a long while. If your lattice is infinite and not noetherian (e.g. doesn't fulfill the 'all ascending chains stabilize'), this might not terminate.
