-Test for Java Developers (Level 1)
+Please, take a look to interface com.getintent.interview.MonochromeScreen and it's 
+documentation. You should:
+
+  * Clone repository
+  * Implement the interface partially: only init() and drawHorizontalLine() methods should be implemented. All others would throw UnsupportedOperationException
+  * Please, use as least memory as possible. The key problem here is finding efficient memory structure
+  * Also please implement unit test for you implementation (use any library you like)
+  * Ideally, you make a fork and pull request on GitHub. Archiving you local repository and sending to us also works.
