/*
** Implementation of a special SQL scalar function for testing tokenizers 
** designed to be used in concert with the Tcl testing framework. This
** function must be called with two arguments:
**
**   SELECT <function-name>(<key-name>, <input-string>);
**   SELECT <function-name>(<key-name>, <pointer>);
**
** where <function-name> is the name passed as the second argument
** to the sqlite3Fts3InitHashTable() function (e.g. 'fts3_tokenizer')
** concatenated with the string '_test' (e.g. 'fts3_tokenizer_test').
**
** The return value is a string that may be interpreted as a Tcl
** list. For each token in the <input-string>, three elements are
** added to the returned list. The first is the token position, the 
** second is the token text (folded, stemmed, etc.) and the third is the
** substring of <input-string> associated with the token. For example, 
** using the built-in "simple" tokenizer:
**
**   SELECT fts_tokenizer_test('simple', 'I don't see how');
**
** will return the string:
**
**   "{0 i I 1 dont don't 2 see see 3 how how}"
