Category vs Collection Confusion

[timotius02]

It is pretty easy to confuse these two terms with each other when going through the project.

For example, in the main sidebar, the UI shows "Choose a Category" but iterates over "Collections".

Also another confusing thing is that the db hierachy for product is: Collection -> Category -> SubCollection??? -> Product. The expectation here is that a SubCollection should follow Collection.

Kind of nitpicky but it does make understanding the project much more difficult to grok immediately. I'd suggest just swapping Collection & Category.
