Tokenizer for email addresses

[egbagirl]

Is your feature request related to a problem? Please describe.
Working with data collected from online form fills, need to mask email addresses as they are collected, but once i do this using the tokenizer built for names, i can no longer parse nor analyze the domain.

Describe the solution you'd like
The tokenizer should applied to both parts of an email address, while maintaining the '@ 'sign. Alternatively, allowing the user to determine what part of the email address requires masking (either the username or the domain address).
This way analysis can still be performed on either parts without compromising the identify of the user.
