Create meta boxes by creating and calling a function but without needing to reuse all of the same WordPress functions for doing so.
Q. How are labels generated? A. When you create a title in the titles array and it is passed into the makeTitles function the name of your meta box gets appended to the begining of the title along with an underscore. Thus if your neta boxe name is 'my_meta_box' and one of your titles is 'My Checkbox' the label for that input will become '_my_meta_box_my_checkbox'.
