loop extrusion example

[SorenKyhl]

I've tried to get the examples/loopExtrusion/extrusion_3D.ipynb example going, but I've run into an error. The jupyter notebook tries to read in LEF positions from a "trajectory" directory that doesn't seem to exist. Is this example up to date?

I think this problem arises because the extrusion_3D code can only be run after first running a 1D loop extusion simulation.

Try to:

• First run extrusion_1D_newCode.ipynb. This should make the file you need.
• Then run this again.
