 * @author Adam Torgerson
 * @brief printf (subset) implementation for the node.
 * @date 12/12/2003
 *
 *
 * This is a subset of printf used for debugging on the node.
 * Minimum field width and zero-padding are available for numeric types.
 *
 * Note: There are a few stipulations with using our version of
 * printf over the normal system printf.
 *
 * use \%C for 8-bit numbers \n
 * use \%d for 16-bit numbers \n
 * use \%l for 32-bit numbers \n
 * use \%c for characters \n
 * use \%s for strings \n
 * use \%b for binary \n
 * use \%h for hexadecimal
