Aspecjt integration for annotation base authorization

Here's the code I'm donating to the Shiro project to use aspectj as the aop kit to perform authorization of method invocation based on the defined Shiro's annotation.

The zip files contains the following:

• java/src: source files to adapt an aspectj joint point to a shiro method invocation
• java/test: unit test classes
• conf: configuration file for the test cases

To compile and run properly, the code requires the following:

• junit jar
• shiro jar
• aspectj jars (I used AJDT within eclipse, so everything was integrated)
