Added Python for FLUTE (for fast RSMT in HFNS). 

* New: In flute, added a Python binding. Contains two methods: "readLUT()",
    to load the POWV9.dat and POST9.dat and "flute()" to build a RSMT.
    "flute()" takes a tuple of positions (themselves 2-uple) like:
        ( (x0,y0), (x1,y1,), ... (xN,yM) )
    and returns a tuple of 3-uple of branches:
        ( (n0,x0,y0), (n1,x1,y1), ... )
    In "flute.h", set the distance type (DTYPE) to int64_t to always
    accomodate DbU::Unit.
      As it now uses the Hurricane Python interface and the path utilities
    from CRL Core, move it's compilation *after* them (see build.conf in
    bootstrap).
