Plotfiles and Other Output
==========================

The following inputs must be preceded by "amr" and control frequency and naming of plotfile generation as well
as which variables will be written out.
as whether the EB geometry or level set should be written out, and if the particles should be written out in Ascii
format (for debugging).
