====== How use a ROOT constructor which needs pointers as arguments in python======

For example to create a histogram with variable bin width, the constructor needs a pointer to the array of the lowEdges (xbins).
<code>
TH1D::TH1D(const char* name, const char* title, Int_t nbinsx, const Float_t* xbins)
</code>

To make pyRoot understand the pointer use the **array** class.
<code>
from ROOT import *
from array import array

binLowE = [2,4,9,15,20,22]
uniformTau = TH1D("uniformTau","",5,array('d',binLowE))
</code>
