+/** \class SpeedFunctionPathInformation
+ * \brief  PathInfo class for encapsulating information about a path 
+ * for a SpeedFunctionToPathFilter Object.
+ * The points are stored as follows: end, start, way0, way1, ..., wayN.
+ * Fronts are propagated in reverse order: wayN, ..., way1, way0, start.
+ * (NOTE: a front is never propagated from end).
+ *
+ * The user must provide at least one PathInfo object using 
+ * SpeedFunctionToPathFilter::AddPathInfo().
+ * If multiple PathInfo objects are added,
+ * multiple paths are extracted and saved to separate filter outputs.
