Enumeration (rxmicro-validation 0.9 API)

```
@Documented
@Retention(SOURCE)
@Target({FIELD,METHOD,PARAMETER})
@ConstraintRule(supportedTypes={java.lang.String.class,java.lang.Character.class},
                validatorClass={EnumerationStringConstraintValidator.class,EnumerationCharacterConstraintValidator.class})
@SelfDocumented
public @interface Enumeration
```
The annotated element must be an element of the predefined enumeration.
This validation rule is useful when java enum type is not applicable.
For example if enum value equals to java keyword. The following enum couldn't be compiled, because 'new' is java keyword
```
 enum OrderType {
      new,    // compile error
      old
 }
 
```
To solve this issue use @Enumeration annotation, otherwise use Java enum.
