Create a PathGeneratorConfigurator on sLTM so we can configure more generally how we generate the paths

[MarkRaadsen]

• move the path filter in there
• have options on how many initial paths to generate and with what algorithm
• have options on how to vary link costs to generate more alternatives
• have options on how often to generate new paths
• have options on when to stop generating new paths
• have options on maximum number of paths for an OD ...etc.

[MarkRaadsen]

• [ ] do stochastic with configuration on how to set that up
• [ ] limit search by OD distance (have bins of max paths by distance map or something along these lines)
• [ ] filters in this configurator as well
