Removed Arrayz.forEach(). Instead use one of
	Stream.of(arrayOfObjects).forEach(action);
	Arrayz.stream(arrayOfPrimitives).forEach(action);
Abandoned Arraz.map(). Instead use one of
	Stream.of(arrayOfObjects).map(f).toArray(ResultType[]::new);
	Arrayz.stream(arrayOfPrimitives).map(f).toArray(ResultType[]::new);
removed unnecessary line of code
Added type Class<?> to toString(Object), i.e. recognizes
java.lang.String, byte[][], void, Void, etc.
Fixed a bug parsing parameter types of lambda signature.
