/**
 * Evaluates the supplied script under the clojure runtime.
 *
 * @param allowedClasses a set of class names filtering which objects can be accessed. Note: restricting class
 *                       access is not supported by this executor, so this parameter must be null or empty.
 * @param inputObjects   a map of input object names and values to expose to the script during execution.
 * @param outputNames    a set of output names to exopse to the script during execution. Note: is expected that the
 *                       script is aware of these names and returns a map accordingly containing all relevant entries.
 * @param script         the script to execute.
 *
 * @return the result of executing the supplied script and extracting the map entries specified by outputNames from
 *         its result./*  w  ww.  j  a v a 2  s  .  c  om*/
 *
 * @throws ScriptingException if an error occurs while executing the supplied script.
