* match_complete

* string Input string to match
* pt Vector of commands (array of cligen object pointers (cg_obj)
* pt_max Length of the pt array
* maxlen Max length of string
* OUT
* cvec cligen variable vector containing vars/values pair for completion
* RETURNS:
* -1 - Error
* 0 - No matches, no completions made
* 1 - We have completed by adding characters at the end of "string"
