Repeat a block of code if an exception is thrown. This is useful in situations where you are creating a database object
with a random token, and you want to repeat the code if the random token happens to exist. The wait
attribute can set a timespan
to wait between attempts, which may be appropriate for connecting to servers, for example.
If an exception occurs, after times
attempts, then it will be thrown normally.
