Overview

Main class to interact with. In fact this is the only class you should interact with when using the library.

Usage example

mail_diff = MailDiff::Diff.new(udiff)
mail_diff.to_html

Keep in mind that Diff will automatically escape all HTML tags from the intput string so that it doesn’t interfere with the output.
