/*
	Serial LCD library for Sparkfun.com Serial Enabled 20x4 LCD
	Revision:	1
	Date:		2011-12-19
	Author: A.Spiridonov

	Based on SfLCD2 code (Rev. 1 is essentially SfLCD2 modified into a library)

	Initialization:
		Initialize by creating a global object of the class,
		then in setup() pass the desired serial by reference
			Example:
				SerialLCD LCD;
				...
				void setup(){
				...
					LCD.begin(&Serial1);
				...
				}

	Functions:
		void print(char *theText);
			- prints the passed char array over 4 lines(if necessary).
			  Automatically truncates to 80 characters (20x4)
			Example:
				LCD.print("This text will appear over multiple lines.");
		void printLine(int lineNum, char *theText);
			- prints the passed char array on the desired line
			  Automatically truncates to 20 characters
			Example:
				LCD.printLine(1, "foo");
				LCD.printLine(2, "bar");
