another style question: label at top

[shaunc]

In my favorite editor, the tabs at top labelled "component" are not very helpful

So I like to put some sort of comment at the top indicating what is in the file. I have been doing this somewhat "ad hoc" ... and have been inconsistent. Also the files have moved. Do we want to standardize somehow?

E.g. How about:

/** @module ember-component/component/ember-component */

yui-doc readable and giving import path?
