Merge branch 'master' into debug

Changelog.md

@@ -6,8 +6,14 @@
 - Added: ToArray/pushTop functions to Stack.class.
 - Added: ComputeNonDefault functions which will contain the current behavior of the Compute function, while the Compute will be changed to be more java compliant!
 - Added: List.reversed, which returns a SubList that has all elements in reversed order and also inserts reversed.
+- Added: Iterators.infinite as an option that will create a Infinite Iterator based on the inputed one.
+- Added: List.indexedIterator which allows you to create a iterator with a customized iteration indecies. Useful if you want to transform lists output.
+- Added: PriorityQueue.contains is now a function
+- Added: Iterators/Async Builders now support MapToPrimitiveType function on the object variant. So more processing can be done. (Will be expanded upon later versions)
 - Fixed: SetValue wasn't working on forEach implementations.
 - Fixed: Compute functions now perform with primitives more java compliant. Meaning that getDefaultReturnValue function no longer is seen as null.
+- Fixed: Supplier was using the wrong dataType in their function name.
+- Updated: SimpleCodeGenerator 1.3.0 is now being used which allows for iterative code support.
 
 ### Version 0.8.0
 - Added: getFirst/getLast/removeFirst/removeLast to Lists
