title: Compare strings with a wildcard
body: <p>I need to compare a couple of strings with eachother. </p>
  
  <p>I have a wildcard character '%' that can substitute any number (the number can be of any size).</p>
  
  <pre><code>string str1 = "STRUCT[1].VARSTRUCT[10].VAR[1]";
  string str2 = "STRUCT[%].VARSTRUCT[%].VAR[%]";
  string str3 = "STRUCT[%].VARSTRUCT[%].VAR[2]";
  
  CompareStrings(str1, str2); // Should return TRUE;
  CompareStrings(str2, str3); // Should return TRUE;
  CompareStrings(str1, str3); // SHould return FALSE;
  </code></pre>
