Provides several data structures to represent a text using a ropes-like structure and manipulating it

var InfiniteString = function(ch, it) {
	this.ch = ch || null;
	this.it = it || null;
};

InfiniteString.prototype.hasNext = function () {
	return true;
};

InfiniteString.prototype.next = function () {
	if(this.it != null  && this.it.hasNext())
		return this.it.next();
	else
		return this.ch;
};

module.exports = InfiniteString;
