This module is essentially empty. It contains no useful code or data, but serves as
a template for creating new modules. One can create a new module by:
1) make a copy of the template 
	>> svn cp module_template my_module
2) change module name in several files:
	./module.properties
	./java/unit_test_info.txt
	./unit_test_info.txt
3) create your own useful content

and external native libraries.

This template contains a small java class and unit-test. It is small but fully functional.
