\brief Tokenize the source code described by the given range into raw
lexical tokens.
\param TU the translation unit whose text is being tokenized.
\param Range the source range in which text should be tokenized. All of the
tokens produced by tokenization will fall within this source range,
\param Tokens this pointer will be set to point to the array of tokens
that occur within the given source range. The returned pointer must be
freed with clang_disposeTokens() before the translation unit is destroyed.
\param NumTokens will be set to the number of tokens in the \c *Tokens
array.
