******************************************************************************
**
** This file contains code for the "fts5tokenize" virtual table module.
** An fts5tokenize virtual table is created as follows:
**
**   CREATE VIRTUAL TABLE <tbl> USING fts5tokenize(
**       <tokenizer-name>, <arg-1>, ...
**   );
**
** The table created has the following schema:
**
**   CREATE TABLE <tbl>(input HIDDEN, token, start, end, position)
**
** When queried, the query must include a WHERE clause of type:
**
**   input = <string>
**
** The virtual table module tokenizes this <string>, using the FTS3 
** tokenizer specified by the arguments to the CREATE VIRTUAL TABLE 
** statement and returns one row for each token in the result. With
** fields set as follows:
**
**   input:   Always set to a copy of <string>
**   token:   A token from the input.
**   start:   Byte offset of the token within the input <string>.
**   end:     Byte offset of the byte immediately following the end of the
**            token within the input string.
**   pos:     Token offset of token within input.
