/*
    This file defines the ProjectorCommand interface.

    It says, "if you want a class you wrote to also be a ProjectorCommand,
    it must have a method ```run``` which takes a ProjectorApplet and
    returns a boolean".

    You can quickly make a ProjectorCommand by using the syntax

     yourLocalVariable = 5;
     ProjectorCommand yourCommand = (ProjectorApplet p) -> {
        your(yourLocalVariable);
        code();
        here();
    }
    return yourCommand;
 */

public interface ProjectorCommand {
    boolean run(ProjectorApplet p) throws ProjectorCommandException;
}
