+ 
+ PREFACE:
+ 
+ Doing UISearchController integration on tvOS is a nightmare. as is ANY integration with the keyboard or having it presented to the end user.
+ I made an attempt to get a more native UI/UX to tvOS for this part but couldn't wrap my head around a way to get it to work in a reasonable amount of time
+ so i came up with this kludge to get search working in a reasonable sense as quickly as possible for tvOS.
+
+ IMPLEMENTATION:
+ 
+ This UIButton is added as the view of a UITabBarButtonItem as the left bar button item & there is a zero rect text field embedded in this button,
+ this is the chicnary necessary to get a keyboard to appear reliably when the text field becomes the first responder.
+ the drawback to this approach is the view appears in a mostly opaque and newly minted UISystemInputViewController with a UIKeyboard on it.
+ to make this approach workable I wait for 0.1 seconds and then decrease the alpha value of the 'topViewController' which happens to be
+ our UISystemInputViewController. this allows the user to see the changes update underneath the view while the search is executed!
