## Background to Problem

I have the below database layout, but I want to be able to have a 'menu'
so that if you are viewing 'Cantelever' below, you have a clickable menu
that can take you to the other parent levels.

For example: Shimano -> Brakes -> Cantelever
where Shimano links to /category/id/1
Brakes links to /category/id/2
and Cantelever (which is the current level) may or may not link
to itself (I haven't decided).


## Current Database Layout (Object Levels)

Object Level ID | Object Level Name | Object Parent ID | Object Menu Level

       1             Shimano                0                  1

       2             Brakes                 1                  2

       3             Cantelever             2                  3

       4             V-Brakes               2                  3
