Wally's Widget World has seen an explosion in growth after a well$-$known influencer, showed off a widget as part of a $15-$second dance that went viral. Wally has hired a bunch of new sales people and wants to keep track of their sales.

Create a class that maintains data for a single sales person, with attributes for the salesperson ID $($example: $3763$ST$),$ the salesperson's full name, the quantity of widgets that individual has sold, and the total revenue generated. Encapsulate those attributes, giving "read" $($get$)$ access to everything, as well as "write" $($set$)$ access to the ID number and name. The quantity attribute should have a method to add to the persons total, and that method should also update the total revenue $($quantity sold times $$9\mathrm{.}99).$
