Lack of unit testing

[gorkemmulayim]

Currently we are testing our system by hand. This a an important issue because we are not able to cover every part of the system. In order to provide more reliable system we must have unit tests which will ensure
the reliablity of the system.

Source code of Tilki does not have a single unit test. For better improvement on Tilki we must provide unit tests for the source code. From now on we use JUnit framework to test our source code. Further improvements should be slowed down until we integrate the current source code with proper unit tests.
