Solver Isomap for QF_BV

In this diagram two solvers are close if they are similar with respect to their solving times at the competitions. See below for a detailed explanation. The trail connects the annual versions of a solver.

1. Fetch all the competition results for the given logic.
2. If requested (it is), remove the solvers that have less than 100 benchmarks in common with 50% of the other solvers.
3. Compute the distance between each solver pair. It is the cosine distance between the wall-clock time of the common benchmarks. More precisely, when if two solvers have n benchmarks in common, we use an n-dimensional space. The coordinate of each solver is the wall-clock time for each benchmarks regardless of the result. The cosine distance is then the angle between the two solvers at the origin.
4. Compute a standard Isomap from the cosine distances.
