A Struct is a convenient way to bundle a number of attributes together, using accessor methods, without having to write an explicit class.
The Struct class is a generator of specific classes, each one of which is defined to hold a set of variables and their accessors. In these examples, we’ll call the generated class ``CustomerClass,’‘ and we’ll show an example instance of that class as ``CustomerInst.’‘
In the descriptions that follow, the parameter symbol refers to a symbol, which is either a quoted string or a Symbol (such as :name).
