The assignment for today's lab is to design a Watch.

A Watch has: 

  a) data: two instance variables, one for hour and one for minute 

  b) behaviour: 

     -- report: prints the time when asked (like report in Account)

     -- tick: deposit one minute into the Watch

  c) should be constructed with an initial time

Example:

 > a = Watch("15:34")
 > b = Watch("09:59")
 > a.report()
 15:34
 > a.tick()
 > a.report()
 15:35
 > b.report()
 09:59
 > b.tick()
 > b.report()
 10:00
