.tpl file output using theme function

So, you have prepared the output in one of your module function with all complicated business logic client specified in last meeting.  Your "return ($output);" throws everything on screen. You became glad to see your code worked finally.
And if Table layout is required you pushed all html in $output variable and theming of your own module page become hectic. Better to go with tpl output.
