// a function like this our other code looks "normal" almost as if its referencing a global.
// This function is not necessary but it makes the code in the main form which references this
// datamodule a lot neater.
// Without this function ever time we would reference this datamodule we would use:
//   TDataModule1(WebApplication.Data).Datamodule.<method / component>
// By creating this procedure it becomes:
//   TDataModule1.<method / component>
// Which is just like normal Delphi code.
