Removed colorama from the installation instructions since it was removed as a dependency
Add a method to pepa_model (and correspondingly to solvers/solution) to calculate utilisations. So for each component a dictionary is returned which maps the component state names to the percentage of time spent in that state
Added a command-line flag to the cli application to allow the calculation of state utilisations. Additionally a pretty printer for those state utilisations
Moved the calculation of utilisations from solution.py to pepa_model.py since in this way the solution could change quite a bit but this would still work.
