The POM and other configuration files have been updated to support a new
execution mode where Cargo is used to execute the backend and NPM to
execute the frontend, both in auto-redeploy mode.

The example done for JavaScript, were people can be managed, has been
migrated to Angular.

The user authentication was currently done using a cookie and following
the same style of token as the HTTP Basic authentication (i.e. a
concatenation of user and password joined with a ':' encoded with
base64).

This authentication has been replaced by a standard HTTP Basic
authentication.

A big refactorization has been done in this commit, focused on
simplifying the testing and execution process. The Spring-DbUnit library
has been added to allow the use of DbUnit through annotations in the
test classes. This change has been complemented with two new test
listeners that allow the creation of custom initial contexts and the use
of custom SQL scripts to create and destroy the database tables before
and after the test execution, respectively. In addition, all the tests
are executed now using a HSQLDB database.

The datasource configuration has been pulled out of the project, and now
it must be provided by the container.

The sample classes have been reviewed, refactorized and documented with
JavaDoc.

The POM file has been reworked to ease test and application execution
using maven. The new execution modes are:
	- The default execution includes unit, integration and acceptance (with
Selenium) test execution.
	- No acceptance tests: mvn -P -acceptance-tests-cargo <phase>
	- Run server for manual acceptance tests: mvn
-Dcargo.tomcat.start.skip=true -Dcargo.tomcat.run.skip=false
-DskipTests=true pre-integration-test 
	- Run server with MySQL database: mvn -P
run-tomcat-mysql,-acceptance-tests-cargo -DskipTests=true package
cargo:run

Web configuration for REST services and login filter was moved from the
web.xml file to code annotations.

POM was reviewed to update the dependencies of the project to the last
version and to improve the test execution.

Now it is possible to run the project with the testing database in a
Tomcat Server v7.0 using the mvn tomcat7:run goal. In addition, Selenium
tests now are executed as integration tests, starting the web server
before the test execution and stoping it after the tests end. Finally,
support for generating regular and cobertura test reports in HTML format
was also added.

The project was also cleaned by removing the MANIFEST.MF files and by
reallocating the SQL files.

Access to any resource except index.html can be restricted enabling the
LoginFilter in the web.xml configuration file. It is currently disabled.

Old index.html moved to main.html and replaced with an index.html that
contains a login form.

RESTful API modified to use PUT, DELETE, POST and GET methods.

In this first version, this applicacion includes a complete CRUD using
an AJAX+JSON+REST architecture.
