<p>Compares a language tag against a list of language tags and selects the most suitable tag according to the rules of RFC 4647 Section 3.4.</p>
<p>The arguments consist of <em>choices</em>, a list of tags from which to select, and <em>priority</em>, a list of acceptable language ranges. Both lists must be sorted in descending order of preference.</p>
<p>The matching algorithm works as follows: </p>
<ol>
<li>
For each item in the <em>priority</em> list, the <em>choices</em> list is scanned for matches. The wildcard value "*" is ignored in lookup operations, as it would match any tag. If a match occurs, the lookup is complete and the matching <em>choices</em> list index is returned. </li>
<li>
If no match has been found, the last subtag on the current <em>priority</em> item is truncated, and the <em>choices</em> list is scanned again. Single-character subtags are also truncated if they are at the end of the tag. This repeats until there are no subtags remaining. This fallback behavior can be skipped by specifying the LookupFlagsNoFallback flag. </li>
<li>
If neither the current <em>priority</em> item nor any of its fallback values matched the <em>choices</em> list, then the next item in the <em>priority</em> list is considered according to the above steps. </li>
<li>
If none of the <em>priority</em> items match the <em>choices</em> list, then a value < 0 is returned. </li>
