refs #1 - Created new project and modules.

 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 project and the modules have pom.xml files and basic directory structures of maven. And index.jsp has be created 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, package 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 have put into each empty directory to commit into GIT, and .gitignore has be created to support development with Eclipse. Also IntelliJ IDEA maybe supported
