I have seen it done both ways. For the purposes of this class let's
standardize on name of the class first, then variables, then methods
(i.e. the opposite of C++ convention). This is more common. I updated
the slides to match this.

Methods and variables sections are optional and may be omitted on a
diagram as it is done on several diagram examples. Also, the return
type and parameter argument types for methods are optional. However,
if they are stated, the prevalent convention is:

  methodName(arugmentName: argType): returnType
