// substr(str, pos [,length])

// Resume : Substract a substring from a bigger string.
// str : The original string
// pos : The index of the position where the substring will begin.
// length (optional) : The length of the substring. If not specified, the substring will continue until the end of the string.

// separator : The separator which cut the string (default is " ").
// Note : Nowadays it's impossible to get a vector of words because we can't append data in a vector.
