Simulation post processing:

• FeatureExtraction_Association_PointToPointAssociation: Functions are provided to determine matches between data sets of (X,Y) points, store and compare groups of associated points (patch objects), and determine intersections between patch objects and circular arcs (useful for collision detection).

• FeatureExtraction_SafetyMetrics_SafetyMetricsClass: MATLAB code implementation of functions that perform safety metric calculations given a set of objects and a path through them.
