// generate an XPath expression for an element in an HTML document

// ONLY WORKS FOR ELEMENTS SO FAR, NO FANCY NODE TYPE SELECTION YET

// for an element tree structure such as
// <a><b><c><d id="test"> this is <e> embedded </e> text </d></c></b></a>
// the XPath expression for window.test (id="test") should be
// //BODY[1]/A[1]/B[1]/C[1]/D[1]

// program proof that loops with changing random length converge on square root
// of max length (from a Tweet the other day that jonathan blow responded to).

// T asked why programmers think a loop with length reset to random * 100 will
// average to 50 instead of 10 (well, actually, it will converge on the square
// root of max plus 2, given the first two steps always execute).
