Description:
	Contains SQL used to create the "Format_Height" function.
	
	This function takes a decimal representation of a height
	value and returns a properly formatted string value. 
					
	For example, a height of 5 feet 9 inches, which would be 
	passed in as the decimal 5.90, would be returned as 5'9". 
					
	Similarly, a height of 4 feet 11 inches, which would be
	passed in as the decimal 4.11, would be returned as 4'11".
