Functional test for accuracy of map matcher

[nreinicke]

Create a functional test that can assess the accuracy of a particular map-matcher. This probably has to be done with respect to a particular road network.

An idea for how to do this:

• create / download a set of sample traces that have a variety of frequencies / noise.
• manually identify which points should go with which road network link
• run a matcher over the sample traces
• compare the matcher results to the hand-built results to define how accurate the matcher did (with respect to human classification).

What issue does this close? Can we tag this with the issue number?

Another idea would be to try to request the pre-labeled data discussed in this publication: https://yifangyin.github.io/publications/PosisiL.Grab.pdf and then validate the accuracy of our map matching algorithms by running them against the dataset.
