day two - finished all required functionalities and able to pass all tests and sample input data
day three - moved report logic out of robot class so that we can implement different reporting methods
day three - get fancy report working and unit tested
day four - grouped all tests under "unit" directory and added testsuites to run all test together, also added Rakefile to that we can run test cases using rake
day four - added extra information on the fancy report so that we can easily identify row and column numbers
day four - fixed a bug found when using command "place" without parameters, added test case to verify it, and also added README.md file to testing instructions
day four - updated docs, added intro text on start up and also fixed another bug when 0 value of width and height are passed when initialising tabletop
day five - refactored the command class so that it will be easy for us to add new commands in the furture
