Revisit incremental calculation
A first draft of incremental calculation is available in the code (class AbstractAlgorithm). However, this still does not care about node states.
We should re-visit the incremental isochrone calculation and take care about the node states.
It would also be great to extend the calculation from isochrone duration to:
different walking speed different starting time different query point If this is done isochrone-web should be extended by a slider for the properties to demonstrate the faster calculation when using incremental calculation. This could be done by using a checkbox which enables/disables the incremental calculation...
