## trim

removes characters from both ends of string argument
trim ( str string, [trimchars string]);
Description

trim returns a copy of subsequence of string str with all the characters present in trimchars trimmed off from the beginning. If the second argument is omitted, it is a space ' ' by default.

rtrim is similar except that it trims from the right.

trim trims from both ends.

    concat('*',trim('   SIMURG   '),'*') -> '*SIMURG*'
    ltrim('AbracadabrA','bAr')  -> 'acadabrA'
    rtrim('AbracadabrA','bAr')  -> 'Abracada'
    trim('AbracadabrA','bAr')    -> 'acada'
