travelr: Functions for Travel Demand Modeling

Provides a suite of functions for building travel demand models, with C/C++ support. Includes fast routines for common operations that are specific to travel demand modeling including gravity model, iterative proportional fitting (Fratar/Furness), network path building, and highway assignment (several common and contemporary equilibrium assignment algorithms are implemented).
