Detailed Description

The "a(symptotic)-alpha PTG", as named in PTG papers.

Compatible kinematics: differential-driven / Ackermann steering
Compatible robot shape: Arbitrary 2D polygon
PTG parameters: Use the app ptg-configurator

This PT generator functions are:

$v(\alpha) = V_{MAX} e^{ -\left( \dfrac{\alpha-\phi}{cte_{a0v}} \right)^2}$

$\omega(\alpha) = W_{MAX} \left( -\dfrac{1}{2} +\dfrac{1}{1+ e^{ - \dfrac{\alpha-\phi}{cte_{a0w}} } } \right)$

So, the radius of curvature of each trajectory is NOT constant for each "alpha" value in this PTG:

Evals the robot clearance for each robot pose along path k, for the real distances in the key of the map<>, then keep in the map value the minimum of its current stored clearance, or the computed clearance.

In case of collision, clearance is zero.

Parameters

[in,out]	tp_obstacles	A vector of length `getAlphaValuesCount()`, initialized with `initTPObstacles()` (collision-free ranges, in "pseudometers", un-normalized).
[in]	ox	Obstacle point (X), relative coordinates wrt origin of the PTG.
[in]	oy	Obstacle point (Y), relative coordinates wrt origin of the PTG.

Note: The length of tp_obstacles is not checked for efficiency since this method is potentially called thousands of times per navigation timestap, so it is left to the user responsibility to provide a valid buffer.; tp_obstacles must be initialized with initTPObstacle() before call.
