Add the findfcl script as a utility rather than having people write their own

[hschellman]

Can we have findfcl as a utility

Here is the command (from the Larsoft tutorial)

#!/bin/bash

if [ $# -ne 1 ]; then
echo "Error: please pass a fcl name (or regex)"
exit 1
fi
if [ -z ${FHICL_FILE_PATH+x} ]; then
echo "Error: FHICL_FILE_PATH has not been set!"
exit 2
fi
SEARCH_PATHS=echo $FHICL_FILE_PATH | sed 's/:/\n/g'
for THIS_PATH in $SEARCH_PATHS; do
if [ -d $THIS_PATH ]; then
find $THIS_PATH -name $1
fi
done
