#### Version 1.5.7

* New Feature: Add integration Timeout Middleware, support DotWeb.UseTimeoutHook to use it
* Detail:
  - Provide DefaultTimeoutHookHandler to simplify use, it will auto write log the req info which time out
- Example:
  ``` golang
  app.UseTimeoutHook(dotweb.DefaultTimeoutHookHandler, time.Second * 2)
  ```
* New Feature: Add Mock module, support DotWeb.SetMock to use it
* Detail:
  - Provide StandardMock to simplify use, it implement Mock interface
  - also you can create custom implement
  - you can register MockHandle or register return string
  - register key only support route
  - special: mock mode only effective in DevelopMode
- Example:
  ``` golang
  func AppMock() dotweb.Mock{
  	m := dotweb.NewStandardMock()
  	m.RegisterString("/", "mock data")
  	return m
  }
  app.SetMock(AppMock())
  ```
