You can now change an agent's policy during the simulation.

CrowdSimulator::getFolder() now uses the C++ "filesystem" library. This should fix bug #94, as it can handle multiple folder separator characters.

TODO: test on Linux

Improved the PowerLaw implementation: Now using our own derivation of the TTC gradient, which is slightly different from Karamouzas version.

- Vector2D: Small performance improvement in getLineIntersection().

- Fixed a mistake in the derivation of the agent force. Updated the code comments accordingly.
- Now using dt=2 as proposed in the 1995 paper.

Agent colors can now be set/retrieved via the API.

Trajectory CSV files with orientations (Feature #91)

Added agent colors to XML (Feature #87)

Closes #87

See merge request !112

Added TrajectoryCSVReader, which can read both a single CSV file and a folder of CSV files. It is not used yet elsewhere in the code, but it may be useful in the future.

- Added Trajectory.h that describes a trajectory of positions *and orientations*.
- TrajectoryCSVWriter (formerly csvwriter) now uses this new Trajectory type. Thus, UMANS now adds agent orientations to CSV output.

Note: this color is only used for the UMANS GUI. It does not affect the API.

Moved std::setlocale from APIFunctions to CrowdSimulator. This fixes comma/point issues for the GUI and console application.

- Updated the copyright notice in all code files.
- Updated the COPYING text file.

Resolve "Visualize cost functions"

Closes #89

See merge request !109

- Cost function visualization can now be switched on/off.
- Now drawing the "best sample velocity" and not the actual result of Policy::ComputeAcceleration(). This way, visualization does not affect random number generators.

GUI bugfix: The refresh rate became incorrect when loading a new simulation with a different framerate.

Acceleration-based policy definition
