Revision 1461

updated all the library code to have sensible _init behavior.
Almost all of the library components have a global variable which gets set after init and the functions inside will fail with an error code if init has not been called. Also, the init functions themselves check this variable and will bail out without doing any damage if that init has already been called

    int i;  // index

    int sensor[5] = {IR4, IR3, IR2, IR1, IR5};

    int color[5] = {RED, ORANGE, YELLOW, GREEN, BLUE};

    int ret;

    // flash orbs BLUE 3 times

    for (i = 0; i < 3; i++) {

	orb2_set_color(color[i]);

	// wait for sensor interaction

	while (range_read_distance(sensor[i]) == -1)

	while ((ret = range_read_distance(sensor[i])) == -1) {

	    // stay RED until IR4 sees something

	    orb1_set_color(RED);

	    if(ret == -3) { //library not init'd 

	      while(1) {

		orb2_set_color(GREEN);

		orb1_set_color(RED);

		delay_ms(250);

		orb1_set_color(GREEN);

		orb2_set_color(RED);

		delay_ms(250);

	      }

	    }

	}

	orb1_set_color(GREEN);

	delay_ms(TEST_TIME);
