[boost] BPL: Passing Python subclass instance of C++ abstract class to C++

This is getting embarrassing. I forgot the Python script:

import grid

class testPI(grid.LogPI):
    def __init__(self, mu = 0.0, sigma=1.0):
        self.mu = mu
        self.sigma = sigma

    def logP(self, x):
        mu = self.mu
        sigma = self.sigma
        if(x>0):
            return -0.5*(x-mu)*(x-mu)/(sigma*sigma)
        else:
            return -0.5*(x+mu)*(x+mu)/(sigma*sigma)

if __name__ == '__main__':
    import grid
    gen = grid.CRobLib(10)
    lnorm = testPI(3,1)
    sg = grid.StochasticGrid(lnorm, -10, 10, 20)
    for i in xrange(0,100):
        print sg.draw(gen)

where grid is the Python module containing the wrapped C++ classes.
