Configuration
-----------------------

    BBCoder.configure do
      tag :b, :as => :strong

      tag :ul
      tag :ol
      tag :li, :parents => [:ol, :ul]

      tag :img, :match => /^.*(png|bmp|jpg|gif)$/ do
        %(<a href="#{content}"><img src="#{content}" /></a>)
      end

      tag :code do
        <<-EOS
    <div class="bbcode-code #{meta}">
      <pre>#{content}</pre>
    </div>
        EOS
      end

      tag :url do
        if meta.nil? || meta.empty?
          %(<a href="#{content}">#{content}</a>)
        else
          %(<a href="#{meta}">#{content}</a>)
        end
      end
    end


Options for #tag

* :as (symbol) -> use this as the html element ([b] becomes strong)
* :match (regex) -> convert this tag and its content to html only if the content matches the regex
* :parents ([symbol]) -> ignore this tag if there is no open tag that matches its parents


When you pass a block to #tag it is expecting you to return a string.  You have two variables available to your block:

* meta -> Everything after the '=' in the opening tag (with [quote="Legendary"] meta returns '"Legendary"' and with [quote] meta returns nil)
* content -> Everything between the two tags (with [b]strong arm[/b] content returns 'strong arm')
