constructor

 * Converts all the object in the iterable extracting the named property.

 * @param iterable The iterable containing the objects to be converted
 * @param propertyName The name of the item's property on which the item must have no duplicated value
 * @return A list containing the property's value extracted from the object in the given iterable
