Cactus Code Thorn IOScalar
Authors    : Gabrielle Allen
CVS info   : $Header$
--------------------------------------------------------------------------

1. Purpose of the thorn

This thorn outputs grid variables as scalars as a function on time

Scalars:
Output straight forwardly

Grid functions:
Output the minimum, maximum, L1, and L2 norm versus time.

Ouput files can be processed with either gnuplot or xgraph.

The IO method "IOScalar" is registered which can be called 
by other thorns via CCTK_OutputVarAsByMethod() to output a 
variable without specifying it in the parameter file.
