 2 | Setting up basic project in sparkjava showing how to organize code as MVC in sparkjava.
 3 | 
 4 | Dependencies sparkjava a micro web framework
 5 | 
 6 | <dependency>
 7 |     <groupId>com.sparkjava</groupId>
 8 |     <artifactId>spark-core</artifactId>
 9 |     <version>2.3</version>
10 | </dependency>
11 | 
12 | In Main.java we have all the routes 
13 | 
14 | All the controllers are in controller folder which extends the base Controller class
15 | corresponding to every Controller class there a folder in templates folder 
16 | which contains all the templates related to Controller
17 | 
18 | We are using a hashMap as database which act as a in cache database and in public/asset folder we will be having 
19 | all our static assets.
20 |  
21 | For templating we are using Apache velocity templating library.
