/**
 * Executes by given script by:/*  ww  w .j  av a  2s.c om*/
 *   - Searching both the classpath and the filesystem for the path
 *   - Copying the script at the given path to a temporary file and
 *     performing variable substitution with the arguments using Freemarker.
 *   - Invoking the script with commons-exec
 *   - Converting the input table to CSV and passing this to the process via stdin
 *   - Parsing stdout, expecting CSV output, and converting this to an immutable table
