Details - this is corrections for a few typos et al i noticed while following the tuturial.

breakline.patch : page overflow. breaks the line to avoid it
commas.patch    : this is a secondary sentence (not sure that's the english word) and should 
                  be delimited with commas.
repeated.patch  : the term 'reference element' occurs twice in a row.
typo.patch      : should be self-explanatory.
typo2.patch     : ditto.
unitcube.patch  : as stands, the example is a expensive way to represent the point (1,1).

note that these are git-format patches (i.e. apply with patch -p1)

if this is not where to submit patches (i.e. you'd rather i sent them to the ml or something), don't hesitate to tell me)

One or more files have been attached.
