## Description

# Comments Field

The Comments field inherits from UnstructuredField and handles the Comments: header field in the email.

Sending comments to a mail message will instantiate a Mail::Field object that has a CommentsField as it's field type.

An email header can have as many comments fields as it wants. There is no upper limit, the comments field is also optional (that is, no comment is needed)

## Examples:

    mail = Mail.new
    mail.comments = 'This is a comment'
    mail.comments    #=> 'This is a comment'
    mail[:comments]  #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::CommentsField:0x180e1c4
    mail['comments'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::CommentsField:0x180e1c4
    mail['comments'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::CommentsField:0x180e1c4

    mail.comments = "This is another comment"
    mail[:comments].map { |c| c.to_s }
    #=> ['This is a comment', "This is another comment"]
