You can represent time statements in most western languages where
a prefix and/or suffix is used.

The default case is to use suffix only (as in English), which you
do by providing the `suffixAgo` and `suffixFromNow` settings in
the strings hash (earlier versions of timeago used the deprecated
`ago` and `fromNow` options). If present, they are used.

    2 minutes [suffixAgo]
    2 minutes [suffixFromNow]
