Short transient search examples: Make data
An example to generate data with a short transient signal.
This can be run either stand-alone (will just generate SFT files and nothing else); or it is also being imported from PyFstat_example_short_transient_grid_search.py and PyFstat_example_short_transient_MCMC_search.py
