Rjf/map model

[robfitzgerald]

This PR draft includes the code changes to implement a first class map matching module for RouteE Compass as described in #244.

Status:

• a map module
  • designed to take references of objects containing geometries, no copy req'd
• edge rtree in map model
• storage for geometries in SearchApp
• wire in map module with SearchApp
• pass SearchApp to output plugins, read geometries from traversal output plugin
• cleanup/remove old bits

Still a draft as I review the work and consider whether to roll the rest of #244 into this.
