The "getPath" method residing in the DynPro.scala class has been restructured from its recursive behavior to an iterative one. Enabling this way the computation of long sequence without having to increase the main thread's stack size.
The old "getPath" method has been renamed to "_getPath" in case there's any need of it in the future.
