class Text::Format::Number

parameters for numbering that will control how the numbers are presented when given as [](index).

:offset: The number to add to the index in order to produce the proper index. This is because tag_text indexes from 0, not 1. This defaults to 1.
:postfix: The value that will be appended to the number presented by []. Defaults to nil.
:prefix: The value that will be prepended to the number presented by []. Defaults to nil.

n1 = Text::Format::Number.new(:postfix => ".")
puts n1[0]  # => "1."
puts n1[1]  # => "2.

n2 = Text::Format::Number.new(:prefix => "2.")
puts n2[0]  # => "2.1"
puts n2[1]  # => "2.2"

n3 = Text::Format::Number.new(:offset => 3)
puts n3[0]  # => "3"
puts n3[1]  # => "4"
