Component Sizing

Throughout the GUI layer, the TerminalSize class is used to represent how many rows and columns a given component takes up on screen.

For example, to set the on screen size of a Panel, call the setPreferredSize method and pass in a new TerminalSize:

	Panel panel = new Panel();
	panel.setPreferredSize(new TerminalSize(40, 2));

You can also pass a TerminalSize object into the constructor of many GUI components, for example, the TextBox component:

	// Creates a textbox 40 columns long, 1 row high
	TextBox textBox = new TextBox(new TerminalSize(40, 1))
