 * I’m trying to build a plugin in OOP fashion using Tom McFarlin’s excellent plugin
   boilerplate.
 * In the constructor I have:
 * `add_action( 'end_loop', array( $this, 'hereman1' ) );`
 * In the core funtion area I have:
 * `public function hereman1() {`
 * It is my understanding that a public function should be callable from outside
   the object, but when my single page template trys to call the function I get 
   a Fatal Error that says the function is undefined.
 * I can call the function if my template calls `myobj::hereman1()`
 * What am I doing wrong?

 * Again, perhaps it is that the function was returning a string, rather than using
   echo.
 * I’ll smash this out on the morrow.
 * Thanks

 * Sorry for the lag in replying, it has been quite the week.
 * It was in fact that the function was returning a value that was not getting printed
   properly.
 * When echo was substituted for return in the function, it worked as expected.
 * Thanks for helping me clarify all that.
