add realBacktrace into PageBuilder so errorDump dir name only contains relative actions.
Add option to errorDump snapshot to SpookyContext
Add numElement function in Page
add 2 options in NaiveDriverFactory: user-agent and window resoluion
default page path lookup shows first 3 and last 1 in the backtrace
simplify csvToMap
Add more examples
TestCore set loadImage to true
really huge tuning, bad habit :-<
