Traverses all edges (depth first) of the given MAT tree starting at the given
vertex (represented by a CpNode). Returns the result as an array of
smooth branches, where smoothness is total or within a given tolerance.
Default value tolerance: number = defaultTolerance
Tolerance given as the degrees difference of the unit
direction vectors at the interface between curves. A tolerance of zero means
perfect smoothness is required.
