Bug in lcprimitives.py

[abhisrkckl]

There is an undefined variable "x0" in the LCKernelDensity.integrate function.

It seems line no 1312 is using x0 and x1 instead of x1 and x2.

I am not sure how to trigger this. I came across this during a code cleanup operation.

I don't think I've ever used this module. Maybe @kerrm knows more?

Oof -- thanks for pointing it out, but this code is specific to Fermi timing stuff, and not really for wider use. I am working on a big PR now, and can't really recommend it for scrutiny by others.

This particular bit of code is quite old and certainly a candidate for removal.
