ByteAsyncBuilder (Primitive-Collections 0.8.0 API)

java.lang.Object
- speiger.src.collections.bytes.utils.ByteAsyncBuilder

```
public class ByteAsyncBuilder
extends java.lang.Object
```
The Async API allows you to process collections on a different thread without having to deal with the Multithreading complexity.
It uses the Lightweight Stream Replace API to do its work, which can make it faster then sequential streams.
This feature isn't designed to do Multithreading work, but to allow moving work off the main thread into a worker thread.
So anything executed on this is still Singlethreaded.

How it works is you create the AsyncBuilder using a Iterable of the Type.
Then select things you want to use on the Iterable.
- For example: map/filter/peek/limit/etc

After that you select your action the Iterable should be applied on.
- For Example: forEach/findFirst/matchAny/etc

Then optionally a custom Executor or callback can be applied
At the end either execute or join can be called to start the task.
- execute will return the Task reference so that the task can be traced back.
- join will await the completion of the task and return the return value

During Construction a couple Disposable Builder Objects will be created.
These will be only used during construction.

The Task Object is also pause-able/Interruptable at any moment during the Processing.
A small example
```
 public void processFiles(ObjectCollection<String> potentialFiles) {
        potentialFiles.asAsync()
                .map(Paths::get).filter(Files::exists) //Modifies the collection (Optional)
                .forEach(Files::delete) //Creates the action (Required)
                .onCompletion(T -> {}} //Callback on completion (Optional)
                .execute() //Starts the task. (Required)
 }
 
```
