# = 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 its 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"]
#
