new features

Add the traj module for handling trajectory data. This module includes the following functionalities:

traj_mapmatch(traj, G[, col]) Nearest map matching: Find the nearest point on the road network for each trajectory point.
trajcleandrift(data[, col, method, ...]) Delete the drift in the trajectory data.
trajcleanredundant(data[, col]) Delete the data with the same information as the data before and after to reduce the amount of data.
traj_slice(trajdata, slicedata[, ...]) Slice the trajectory data according to the slice data.
traj_smooth(data[, col, proj, ...]) Smooth Trajectory Using Kalman Filter.
traj_segment(data[, groupbycol, retaincol]) Segment the trajectory in order and return the starting and ending information of each segment.
traj_densify(data[, col, timegap]) Trajectory densification, ensure that there is a trajectory point each timegap seconds
traj_sparsify(data[, col, timegap, method]) Trajectory sparsify.
trajstaymove(data, params[, col, activitytime]) Input trajectory data and gridding parameters, identify stay and move
pointstotraj(traj_points[, col, timecol]) Input trajectory, generate GeoDataFrame
