> This issue tracks improvements to the EnhancementEngineHelper implemented as part of STANBOL-488 (EnhancementProperties) and STANBOL-1334, STANBOL-1334 (DereferenceEngine) that are also useful for any other EnhancementEngine that requires to parse
> * OSGI component configuration (using Dictionary<String,Object>)
> * Enhancement properties (using Map<String, Object>).
> The EnhancementEngineHelper will be extended by the following type of static utility methods
> {code}
>     + parseConfigValues(Object value, Class<T> type) : Collection<T>
>     + parseFistConfigValue(Object value, Class<T> type) : T
>     + getConfigValues(Dictionary<String,Object> config, String property, Class<T> type) : Collection<T> 
>     + getConfigValues(EnhancementEngine ee, ContentItem ci, 
>         Map<String,Object> enhProp, String property, Class<T> type) Collection<T>
> {code}
> All methods will:
> * return NULL if NULL is parsed as config value or the parsed configuration does not contain the requested property
> * support Arrays and Collections for multiple values.
> * support Arrays of primitive types
> Additional optional parameters (for all methods)
> * `String preserveNullValues`: if null values should be preserved. By default those will get removed.
> * `Collection<T> addTo`: Allows to parse the collection to be filled with the configuration values
