 """SiteCompare command to time page loads
 
 Loads a series of URLs in a series of browsers (and browser versions)
 and measures how long the page takes to load in each. Outputs a
 comma-delimited file. The first line is "URL,[browser names", each
 additional line is a URL follored by comma-delimited times (in seconds),
 or the string "timeout" or "crashed".
