  @param configFile The path to the xml (spring) configuration file {@code null} null for default.
  @param propertiesFile The name of the properties file containing the grid's properties.
  You may, of course use Spring's {@code <context:property-placeholder location="classpath:com/foo/bar.properties"/>} but this parameter is helpful when you want to use the same xml configuration
  with different properties for different instances.
