Instance Method Details

#full_name(sex = nil) ⇒ Object

Generates a normal full name, including a middle name.

For now, this is fairly sloppy, as the probability that a middle name will simply be another given name of the same gender is almost certainly less than 100%.

TODO: Make this take into account different probablities of different

types of middle names.
