* Cross-Browser Split 1.1.1
* Copyright 2007-2012 Steven Levithan <stevenlevithan.com>
* Available under the MIT License
* ECMAScript compliant, uniform cross-browser split method
*/
/**
* Splits a string into an array of strings using a regex or string separator. Matches of the
* separator are not included in the result array. However, if `separator` is a regex that contains
* capturing groups, backreferences are spliced into the result each time `separator` is matched.
* Fixes browser bugs compared to the native `String.prototype.split` and can be used reliably
* cross-browser.
* @param {String} str String to split.
* @param {RegExp|String} separator Regex or string to use for separating the string.
* @param {Number} [limit] Maximum number of items to include in the result array.
* @returns {Array} Array of substrings.
* @example
*
* // Basic use
* split('a b c d', ' ');
* // -> ['a', 'b', 'c', 'd']
*
* // With limit
* split('a b c d', ' ', 2);
* // -> ['a', 'b']
*
* // Backreferences in result array
* split('..word1 word2..', /([a-z]+)(\d+)/i);
* // -> ['..', 'word', '1', ' ', 'word', '2', '..']
