Calculate Day

Just a quick something that I threw together to sum my day at work from 6 parameters.

In parameters:

• When the day started. (24h -> hh:mm)
• When the lunch started. (24h -> hh:mm)
• When the lunch ended. (24h -> hh:mm)
• When the day ended. (24h -> hh:mm)
• How many minutes spent on other breaks. (mm)
• A comment about the day. (String)

Output: "#{hh:mm}h, #{comment} /#{possible error}"

This code has not been refactored....

Structure

• bin/ : contains the executable file
• lib/ : contains the actual class file
• spec/ : the examples.
