Public Instance methods

call()

Scans an email body to determine which bits are quoted and which should be hidden. EmailReplyParser is used to split the comment into an Array of quoted or unquoted Blocks. Now, we loop through them and attempt to add <div> tags around them so we can hide the hidden blocks, and style the quoted blocks differently. Since multiple blocks may be hidden, be sure to keep the "email-hidden-reply" <div>s around "email-quoted-reply" <div> tags. Call this on each comment of a visible thread in the order that they are displayed. Note: all comments are processed so we can maintain a Set of SHAs of paragraphs. Only plaintext comments skip the markdown step.

Returns the email comment HTML as a String
