BrillLindquist.c
Log:
Use "epsilon" also for Brill-Lindquist
IDAnalyticBH has an "epsilon" parameter to smooth out singularites.
This parameter should also be used in Brill-Lindquist initial data.
Otherwise, moving puncture evolution of these data is not possible
without an explicit smoothing step.
