visualise Python cProfile data with this kcachegrind converter

 Pyprof2calltree converts cProfile data into a format that is
 consumable by kcachegrind and qcachegrind for graphical calltree
 analysis. This combination provides similar capabilities to Snakeviz
 or RunSnakeRun.
 .
 Pyprof2calltree is an adaptation of lsprofcalltree.py, written by David
 Allouche, Jp Calderone, Itamar Shtull-Trauring, and Johan Dahlin. It
 has been adapted to behave more like scripts in the kcachegrind-converters
 package. One of the authors' objectives is for pyprof2calltree to
 eventually become part of the official upstream kdesdk package.
