Name: extract - extract a substring from a string

Syntax:
	string extract(string str, int from);
	string extract(string str, int from, int to)

Description:
	The extract efun gets a substring from a string. Character 0 is first
	character, charater (strlen(str)-1) is the last.

	If the third argument is omitted, eg. extract(str, n), it will return
	a substring from characer number 'n' to the end.

	If all arguments are given, eg. ectract(str, i, j), it will return a
	string from character i to character j.

Note:
	The function is equivalent to the LPC syntax 

			str[from..to]

	Therefore you SHOULD NOT use extract any more!

Examples:
	extract("random", 3) will return "dom".
	extract("random", 1, 3) will return "and".
