Java Common Extension

# Get it

```xml
<dependency>
    <groupId>com.github.XDean</groupId>
    <artifactId>Java-EX</artifactId>
    <version>0.1.1</version>
</dependency>
```

# Features
## Lang
- Finalize support. Attach clean up tasks on any object. Free from `Object.finalize`.
- Size of object. Measure shallow and retained size of object or class by java code which is useful when debug.

## Reflect
- Add or change annotations on Class/Method/Field at runtime.
- Get explicit generic type of class or interface.
- Get caller (any depth in stack) information
- Get more information of class: getAll(Field/Method/Interface/SuperClass)s, getRoot(Field/Method)

## Collection
- `Either`. Left or right, that is a question.
- `Pair`. Left and right, that is no question.
- `IntList`. Operate int array easier. (not `java.util.List`)
- `TreeNode`. A powerful tree implementation. (not dependable yet)
- `Traverse`. Traverse any tree structure. Provide default PreOrder/PostOrder/BreadthFirst traverser.

## Easy Programming / Function Programming
- Functions with throws.
- Ignore checked exception by `uncheck`.
- Change throw exception to return it.
- Cache everywhere like dynamic field.
- Let everything lambda and let lambda one line:
	- `Try`
	- `If`
	- `TaskUtil`

## RxJava Extension
- From java functions to Rx functions.
- Use `RxNullable` to handle null value easily! ([RxJava2 don't support null value more](https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#nulls) and use `Irrelevant` or `Optional` everywhere is so ugly).
- From `Observable`/`Flowable` to `Iterator`.
- `RandomOperator`. Easy to shuffle.

## Other many utilities
See the code!
