 Documentation:
 * Fix links from tutorial to manual (and reread/tweak)
-* Add DTMC/MDP case to synchronisation section
 * New -exportprism/-exportprismconst/-nobuild switches
-* Check for existence of zero-reward loops
 * New -exporttarget switch
 * Extra reach info switches?
 * Some pointers for where to start with PTAs, e.g. where examples are

 * Games: Optimise number of states in time-bounded PTAs

 * Fix: Creation of new names (adding extra _s) doesn't take into account prop file ot consts etc.
 * Digital clocks: urgency?
 * Digital clocks: optimisations?

 * New version of valid2 (inv/g push outside)
 * Combined complement + intersection (terminating early) for when dbm lists get big
 * Are we ok to have non-diagonal c-closure algorithm?
