SQL to Java Code Generator Code

Added a Velocity reference injection listener. This listener will make sure references are parsed using the StringParser and the current node before they are injected into the template.

I recreated strong-typed dataholders. They are needed because certain functionalities are specific to only one type of dataholder. For example relationships are only a concern of a table.

I also rearranged the dataholders. As they used to be located inside the commons.beans package, the are now moved to the data.holders package.

One major difference from the previous versions is the availability of nodes. Every dataholder is a node and as such, can be located inside the tree by using a path. We can use this later on to address specific nodes.

The 'lister' branch is based on the 3.0 release and as so, it contains all the new features made available in it. It also contains a generic data structure instead of the strong-typed data-holders used in the 2.6 releases.

Adding latest modifications for the 3.0 release. I noticed it really is too hard to create a generic structure to persist the data fetched from the database. I'll try to use strong-typed objects again, so the code will be easier to understand. We'll keep the generic datastructure for a later release.

Added a basic log4j configuration. It isn't perfect yet, but it will do for now

Tried to make a first version work. It needed some modifications in the code to get things done.

basic ant build file based on the one contributed by Charl van Jaarsveldt (charlvj)

Added version control structures to for the ui

added patterns to ignore eclipse project files

added output path
