Better EnumUtils

                 Key: LANG-513
             Project: Commons Lang
          Issue Type: Improvement
    Affects Versions: 3.0
            Reporter: Ivan Bilenjkij
             Fix For: 3.0

Parametrize the getEnumMap() method with <E extends Enum<E>>.  This narrows down
the argument so that non-enums and {{null}} are rejected at compile time. Also, at it current
state the EnumUtils should never be instantiated. 

{} public static Map<String, Enum<?>> getEnumMap(Class
enumClass) {code}

changes to:

{} public static <E extends Enum<E>> Map<String, Enum<E>>
getEnumMap(Class<E> enumClass) {code}
