WordPress safely defining and executing functions

Handy safe way to include functions in your WordPress Themes functions.php file. This is even more useful if you are using a child theme and don't want to conflict with functions already defined by the parent theme. Even better; These functions can be executed within the same if(function_exists()) block that defines them creating a neater to manage functions.php file.I also included some basic stuff you might find handy to have in your own WordPress themes functions.php file.
