Generate usage statistics #34

[x] Add a property to JSSPInstance that collects information about heuristic usage when solving the instance
[x] Add a method to selectionHH that analyzes all solved instances and summarizes heuristic usage information
[x] Validate that selectionHH contains a property with a set of lastSolvedInstances to avoid losing information about the solved instances

First item is to be disregarded (at least for now) since information is kept in perfromanceData within ruleBasedSelectionHH, by storing a copy of partially solved instances. Perhaps this should be changed to a single instance and a simple log of steps taken so that the solution can be moved forward/backward without too much computational cost. For now, it shall remain as it is...

Regarding the second item: The method getSolverUsed was added. It returns a vector with the numerical ID of the solvers used at each step, for a given instance. Additionally, the methods plotSolverUsage, plotSolverUsageDistribution, and plotSolverUsageDistributionMulti were added to generate different kinds of plots with this information.

Last item: The information should be retrievable from the performanceData property, but also created the lastSolvedInstances property for ease of access.
