There is no explicit model type keyword added to the parser.
Instead, LTSs are auto-detected by the absence of probabilities.
ConstructModel is extended to build LTSs. Model checking (CTL+LTL)
can be done out of the box using the existing NonProbModelChecker class.
A few MDP regression tests are clarified to make it clear that the
models are MDPs, not LTSs.
Due to a typo, the upper iteration uses `updateValueFromBelow` instead of `updateValueFromAbove`
to update the value vector. When the flag for monotonicity enforcement from above is active (default),
all values are thus forced to be above the upper bound, preventing convergence.
Example:
prism functionality/verify/mdps/reach/mdp_simple.nm functionality/verify/mdps/reach/mdp_simple.nm.props -sparse -intervaliter
