<p>Given a <code>wordlist</code>, we want to implement a spellchecker that converts a query word into a correct word.</p>
<p>For a given <code>query</code> word, the spell checker handles two categories of spelling mistakes:</p>
<ul>
<li>Capitalization: If the query matches a word in the wordlist (<strong>case-insensitive</strong>), then the query word is returned with the same case as the case in the wordlist.
<li>Vowel Errors: If after replacing the vowels <code>('a', 'e', 'i', 'o', 'u')</code> of the query word with any vowel individually, it matches a word in the wordlist (<strong>case-insensitive</strong>), then the query word is returned with the same case as the match in the wordlist.
<p>In addition, the spell checker operates under the following precedence rules:</p>
<ul>
<li>When the query exactly matches a word in the wordlist (<strong>case-sensitive</strong>), you should return the same word back.</li>
<li>When the query matches a word up to capitlization, you should return the first such match in the wordlist.</li>
<li>When the query matches a word up to vowel errors, you should return the first such match in the wordlist.</li>
<li>If the query has no matches in the wordlist, you should return the empty string.</li>
</ul>
<p>Given some <code>queries</code>, return a list of words <code>answer</code>, where <code>answer[i]</code> is the correct word for <code>query = queries[i]</code>.</p>
