Provides a numbering object that will produce numbers. Accepts three 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"
