crawl: Fit Continuous-Time Correlated Random Walk Models to Animal Movement Data

Fit continuous-time correlated random walk models with time indexed covariates to animal telemetry data. The model is fit using the Kalman-filter on a state space version of the continuous-time stochastic movement process.
