Add a way to load and parse the data to the QIviSimulationEngine

The new loadSimulationData() function can load a JSON file and store
it's content in the IviSimulator singelton.

The IviSimulator singleton provides functions to interpret the JSON
values and other helpers e.g. checking for min/max/domain values.
