Tweak formatting of function DocC comments
Browse files Browse the repository at this point in the history 
Motivation:

Tweaking the formatting of the DocC comments enables syntax highlighting
for parameter names in Xcode

Modifications:

Whitespace changes, capitalisation changes and added a parameter
description for `indexing` in HOACKHeaders `replaceOrAdd`, `add`.

Result:

More readable DocC comments
