Documetation of retry argument

Description

The ability to retry function code is enabled by default. retry can be a logical value. if it is TRUE then noTry = getOption("seleniumPipes_no_try") and delay = getOption("seleniumPipes_no_try_delay"). If it is FALSE the facility to have multiple trys of the function call is removed. retry can also be a list with the following named arguments that will override the values in options

"noTry"

Integer indicating how many times to try the function call

"delay"
