*
* PRECONDITIONS: the values in the Map are either Strings representing fully qualified java class names, or
* java.lang.Class instances.
*
*
* ALGORITHM: Look in the argument map for a value for the argument key. If found, if the value is instanceof String,
* assume the String specifies a fully qualified java class name and obtain the java.lang.Class instance for that String
* using Util.loadClass(). Replace the String instance in the argument map with the Class instance. If the value is
* instanceof Class, proceed. Assert that the value is either instanceof java.lang.Class or java.lang.String.
*
*
* Now that you have a java.lang.class, call its newInstance and return it as the result of this method.

* @param map The Map that will be searched.
