Currently modules are interdependent. We should merge base modules into a single FXGL framework module, which can be used to import as a dependency into a client project. In addition by using classpath search we can add extra functionality like fxgl-net and extra controls / helper classes / code using fxgl-extra. This extra module may contain specific game genre helpers, e.g. RPG. Also we should rethink the package names for merged classes.
