resolves #1 - Created a new project and several modules.

 I want to resolve #1 in this commit that make the application runs on Google App Engine.

 Created a project including several modules to start to develop this application.
 And this application adopt multi layered architecture, and the each layer is placed in each module.
 The web layer module 'lasagna-italiana-war' was configured to run on Google App Engine.
 
 The test project is to support testing application. Some programs which help testing will be placed into the project.
 But now, there is nothing in the project, yet.

 The project and the modules have pom.xml files and basic directory structures of maven. And index.jsp has be added to test.
 The application can be tested on 'devserver' which provided appengine-maven-plugin.
 To launch the 'devserver' and to access index.jsp requires a few steps below:
- In the top directory, execute a command 'mvn clean install' to compile packages and install the application into your system.
- Then move to a directory 'lasagna-italiana-war' and execute command 'mvn appengine:devserver' to launch the devserver.
- At the end, access to a url 'http://localhost:8080/' with your web browser (ex. Google Chrome).

 In addition, .gitkeep files were put into each empty directory to commit into GIT, and .gitignore was created to support development with Eclipse. Also IntelliJ IDEA maybe supported.
