Research direction

The issue names no files or tests. Start by tracing the public vehicle-routing API that accepts cost and duration matrices, then review the related Heterogeneous Fleets issue (#11). Done means multiple vehicles can receive separate costFactors and durationFactors that scale the corresponding matrices, with coverage for the three-vehicle example.

Written by the indexing model from the issue text.

Description

At the moment we expose a single cost and duration matrix per vehicle. What we should allow for in the context of multiple vehicles is cost and duration factors on a per vehicle basis to scale the cost and duration matrix the user passes us, think

numVehicles: 3
costFactors: [1.0, 0.7, 1.5]
durationFactors: [1.0, 0.7, 1.5]

which would scale both the cost as well as the duration matrices depending on the factors for each vehicle. We need to separate cost and duration factors because users could specify e.g. distance as cost in which case costFactors would be [1.0 1.0 1.0] and durationFactors would account for slower and faster vehicles.
