/*
 * Print a single row with 3 columns. 
 * Handy for 2x16, 4x20, or larger displays with multiple rows.
 * 
 * Input:
 *  location = The start location to print the text
 *  text     = Text to print out
 *  row      = What row number to print to
 *  
 *  Example:
 *  LCD Display Setup 
 *  ------------------
 *  |Row 0           |
 *  |Row 1           |
 *  ------------------
 *  0       ->      15 
 *  
 *  Notes:
 *    - be mindful of text length because it can get overwritten
 *      if too long.
