html-template gem - old-style classic HTML template language / engine like it's 1999 (incl. back-to-the-future ERB converter)

Hello,

   I've put together a new old-style classic HTML template language /
engine [1] like it's 1999 that includes a back-to-the-future ERB
converter too.

   The original HTML::Template [2] package was written by Sam Tregar et al
(in Perl with a first 1.0 release in 1999!).

   For a short intro here's the students example from the tests:

  require 'html/template'

   t = HtmlTemplate.new( <<TXT )
<TMPL_LOOP students>
<p>
Name: <TMPL_VAR name><br/>
GPA: <TMPL_VAR gpa>
</p>
</TMPL_LOOP>
TXT

    puts t.render( students: [ { name: 'Bluto Blutarsky', gpa: 0.0 },
                               { name: 'Tracey Flick',    gpa: 4.0 } ])
#=> <p>
#   Name: Bluto Blutarsky<br/>
#   GPA: 0.0
#   </p>
#   <p>
#   Name: Tracey Flick<br/>
#   GPA: 4.0
#   </p>

    Happy text processing and template merging in ruby.

    Cheers. Prost.
