 Menu creation is all about structure. First there are variables/constants that go into the **LiquidLine** objects. Then the **LiquidLine** objects go into the **LiquidScreen** objects. Then **LiquidScreen** objects go into the **LiquidMenu** object/s. And optionally the **LiquidMenu** objects go into the **LiquidSystem** object.
 This structure can be established on object instantiation or later with functions:
 
- - `LiquidLine::LiquidLine(byte column, byte row, A &variableA, B &variableB...); //takes up to 4 variables`
- - `LiquidScreen::LiquidScreen(LiquidLine &liquidLine1, LiquidLine &liquidLine2...); //takes up to 4 lines`
- - `LiquidMenu::LiquidMenu(LiquidCrystal &liquidCrystal, LiquidScreen &liquidScreen1, LiquidScreen &liquidScreen2..., byte startingScreen = 1); //takes up to 3 screens`
