also fix a bug in importing JSON data.

This has not been discussed yet, the name is for now "extraPropertyDict"

naming convention in scheduling rules changed and also LPT and SPT were added. Documentation also updated to this

setWIP added also as global method. It would be better for examples. Also example JobShop1 updated to match new notation

MachineJobShop and QueueJobShop brought in a more generic way. Still there is one issue. If job route may be more than one candidates it will go wrong

MachineJobShop and QueueJobShop updated so that they can act as jobshop objects both in input and output. topologies 18 to 20 updated in the new notation

added antOptimiser and LineGenerationJSONAntOptimise. The first is an optimisation algorithm based on scheduling rules. Second is the main ManPy script that the AntOptimiser calls when he needs to evaluate

Job output updated so that also the delay is outputted. This is done only if a dueDate was given, and delay=compleationTime-dueDate
