Reworked Module Settings System

Changelog:
- Added: Dependency System that will resolve missing classes and enable
them as needed. (This isn't perfect on some low level modules like
Functions)
- Added: Dependency Error system that will throw errors if a dependency
is that is required is specifically disabled.
- Added: Default setting for "undefined" entries.
- Fixed: A few bugs that made the dependency system unnecessary
difficult.
- Updated: Documentation

 # Changelog of versions
 
+### Version 0.9.0
+- Added: getFirst/getLast/removeFirst/removeLast to List.class.
+- Added: Dedicated Set toArray implementations.
+- 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.
+- Breaking Change: Map.compute/IfAbsent/Present and Map.supplyIfAbsent if the value is a primitive it will no longer accept the defaultReturnValue() as "null" if that functionality is desired then use: computeNonDefault which contains the functionality!
+
 ### Version 0.8.1
 - Added: getFirst/getLast/removeFirst/removeLast to List.class.
 - Added: Dedicated Set toArray implementations.

 On top of that:   
-Any Setting that isn't "Present" is counted as "Enabled".    
+Any Setting that isn't "Present" can be defined as "Enabled" or "Disabled" using the "Default" argument.     
+If "Default" is missing, then it will just default to "Enabled".    
 So if you want to disable just 1 thing you can keep that 1 thing and delete the rest of the Setting.    
 It will still work as the same.    
 The default settings just come with everything so you can see what is controllable.   
+Note: If a global Module setting is disabled but a dependency needs said Module, it will enable only the required classes.    
+If a Module type (Float-Collection as example) is specifically disabled, the Dependency Resolver will throw errors telling you whats wrong.
