Town folk

Town folk should play a role in the players town. They should be able to have job classes and provide various roles to your town, for instance:

Architect; The player could go to them and design their buildings (Buildings are something else I need to address)
Builder (or a better name); They build the buildings the player wants to place in their town
Landscapper; Allows the player to plant trees and grass and other such things
Merchant; Sells things in the players town

And so on. They could even have various levels of their job class, such as a builder being able to build a better quality building or some such.
