Added support to retrieve the weekly activity goals for the current user.
Added the ability to update an existing alarm.
Use snake case, since this is Ruby. Also added documentation to each of the alarm methods instead of pointing to the Fitbit wiki page.
Added an option hash as the second parameter to format_time. Show the time with a timezone when :include_timezone is added as an option and set to true. Otherwise just show "%H:%M" as the format.
Use the option hash of format_time to include the timezone in the output of the time.
Colorize the RSpec output.
