//EnhanceJS isIE test idea

//detect IE and version number through injected conditional comments (no UA detect, no need for cond. compilation / jscript check)

//version arg is for IE version (optional)
//comparison arg supports 'lte', 'gte', etc (optional)

function isIE(version, comparison) {
	var cc      = 'IE',
	    b       = document.createElement('B'),
