Enhancement request: explicit waits and expected conditions

[linguinee]

Perhaps something like:

SEWebDriverWait *wait = [[SEWebDriverWait alloc] initWithDriver:driver timeOutInSeconds:10];
SEExpectedConditions *condition = [SEExpectedConditions presenceOfElementLocatedBy:[SEBy id:@"myDynamicElement"]];
SEWebElement *e = [wait until:condition];

sounds good to me, be great if someone opened a PR

I'll look into it when I find some free time - just wanted to put the idea out there. :)
