-/** 
- * @class LLMimeIndex
- * @brief Skeletal information useful for handling mime packages.
- * @see LLMimeParser
- *
- * An instance of this class is the parsed output from a LLMimeParser
- * which then allows for easy access into a data stream to find and
- * get what you want out of it.
- *
- * This class meant as a tool to quickly find what you seek in a
- * parsed mime entity. As such, it does not have useful support for
- * modification of a mime entity and specializes the interface toward
- * querying data from a fixed mime entity. Modifying an instance of
- * LLMimeIndx does not alter a mime entity and changes to a mime
- * entity itself are not propogated into an instance of a LLMimeIndex.
- *
- * Usage:<br>
- *  LLMimeIndex mime_index;<br>
- *  std::ifstream fstr("package.mime", ios::binary);<br>
- *  LLMimeParser parser;<br>
- *  if(parser.parseIndex(fstr, mime_index))<br>
- *  {<br>
- *    std::vector<U8> content;<br>
- *    content.resize(mime_index.contentLength());<br>
- *    fstr.seekg(mime_index.offset(), ios::beg);<br>
- *    // ...do work on fstr and content<br>
- *  }<br>
