python rtree is faster than binning:

{{{
In [1]: run _contW_rtree.py
Completed in:  0.213819980621 seconds using rtree

In [2]: run _contW_binning.py
using ../examples/10740.shp
time elapsed for ... using bins: 0.409120082855

}}}

so we will use rtree rather than binning. check for c rtree is removed.
