Create Enterprise mock pulsars
"""
For simulations one often needs to read in par/tim files. But on some machines
it is hard to install PINT or tempo2/libstempo. And reading in par/tim files is
a bit slow, especially when reading in lots of them. Here we allow use of
Enterprise with mock pulsar.
Generate some mock par files like so:
def example_usage():
import mockpulsar, os
npsrs = 100
