Create a filter module to easily make a standard infobox with essential information.

E.g.:
http://openteacher.info/node/43
has the following infobox:

{
Curriculum: the three "R"s: reduce, reuse, recycle.
Level: beginner students.
Social issues: protecting the environment by understanding and applying the three "R"s.
Copyright: openteacher.info and Augustin Masquilier.
}

Improve the presentation, and make it so that creating one is easy for any contributor.
