Few Developer Notes

1. Lot, Slot and Car are 3 classes used to solve the problem. The classes are added to parking_lot/lib
2. Git's .git directory is present inside the parking_lot directory. So you can check the commits using following command from 'parking_lot' directory: $ git log
3. No new gems were added to the default Gemfile and even no new add on setup is added to 'bin/setup'
4. Unit tests are written under parking_lot/functional_spec/spec directory. These run as a part of test suite with the command given in above section
5. bin/parking_lot executable file takes the input and runs the program
6. Rest of the things are self explanatory, but for any issues you can reach out via email 'raghuboosetty@gmail.com' or on call '9177167375'
