Provide Some simple examples to help using Spray Web Framework with twirl and slick.
1> Use twirl as front template engine. Html files need to be placed in a directory named twirl. For example
src/scala/main/twirl/packagePrefix/object/func.scala.html
Fill the func.scala.html as following
```
@(name: String, age: Int = 42)
<html>
@* This template is a simple html template --- (this text btw. is a comment and is not rendered) *@
<h1>Welcome @name!!</h1>
<p>You are @age years old, @(if(age < 21) <i>shouldn't you be in bed ?!</i> else <i>have a great evening !</i>)</p>
</html>
```
Call packagePrefix.object.func(arg1,arg2) to render func.scala.html
2> Http route
* Response with html with packagePrefix.object.func(arg1,arg2).toString
* Use MyJsonProtocol to respond json content
3> CRUD
Slick provides Table to map table in db, TableQuery to do crud. Await and Future to do IO operations.
