# = References Field
# 
# The References field inherits references StructuredField and handles the References: header
# field in the email.
# 
# Sending references to a mail message will instantiate a Mail::Field object that
# has a ReferencesField as its field type.  This includes all Mail::CommonAddress
# module instance metods.
# 
# Note that, the #message_ids method will return an array of message IDs without the
# enclosing angle brackets which per RFC are not syntactically part of the message id.
# 
# Only one References field can appear in a header, though it can have multiple
# Message IDs.
# 
# == Examples:
# 
#  mail = Mail.new
#  mail.references = '<[e-mail]>'
#  mail.references    #=> '<[e-mail]>'
#  mail[:references]  #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::ReferencesField:0x180e1c4
#  mail['references'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::ReferencesField:0x180e1c4
#  mail['References'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::ReferencesField:0x180e1c4
# 
#  mail[:references].message_ids #=> ['[e-mail]']
#
