class name First char must be UpperCase.
Ioc
1. Register one class will auto register depdence class (must has a class decorator).
2. get Instance can auto create constructor param. (must has a class decorator or register in container).
$3
* in browser can not:
1. use syncBuild
2. syncLoadModule
3. can not use minimatch to match file.
4. support es5 uglify, use typescript-class-annotations to get class annotations before typescript compile.
`ts
let builder = new ContainerBuilder();
// 1. via create.
let container = builder.create();
// 2. via build.
//with BuildOptions to auto register module.
let container = await builder.build({
files: [__dirname +'/controller/*/.ts', __dirname + '/*.model.js'],
moudles:['node-modules-name', ClassType]
});
// 3. via syncBuild
let container = builder.syncBuild({
moudles:['node-modules-name', ClassType]
});

see interface IContainer
`ts
// 1. you can load modules by self
await builder.loadModule(container, {
files: [__dirname +'/controller/*/.ts', __dirname + '/*.model.js'],
moudles:['node-modules-name', ClassType]
});
// 2. load sync
builder.syncLoadModule(container, {
moudles:['node-modules-name', ClassType]

// 3. register a class
container.register(Person);
// 4. register a factory;
container.register(Person, (container)=> {
...

// 5. register with keyword
container.register('keyword', Perosn);

you can use yourself MethodAccessor by implement IMethodAccessor, register symbols.IMethodAccessor with your MethodAccessor in container, see interface IMethodAccessor.
`ts
@Injectable
class Person {
constructor() {
}
say() {
return 'I love you.'
}
}
@Injectable
class Child extends Person {
constructor() {
super();

say() {
return 'Mama';

sayHello( @Inject(Child) personA: Person, personB: Person) {

AOP
It's a dynamic aop base on ioc.
define a Aspect class, must with decorator:
* @Aspect
define advice decorator have
* @Before(matchstring|RegExp)
* @After(matchstring|RegExp)
* @Around(matchstring|RegExp)
* @AfterThrowing(matchstring|RegExp)
* @AfterReturning(matchstring|RegExp)
* @Pointcut(matchstring|RegExp)

export const Authorization: IClassMethodDecorator = createClassMethodDecorator('Authorization');
// auth check simple.

// pointcut for method has @Authorization decorator.

Extend decorator
see interface LifeScope
You can extend yourself decorator via:
1. createClassDecorator
`ts
/**
* create class decorator
*
* @export
* @template T metadata type.
* @param {string} name decorator name.
* @param {MetadataAdapter} [adapter] metadata adapter

@returns {}
*/
