JavaScript template language shootoff

JavaScript performance comparison

Revision 105 of this test case created by Premasagar Rose

Info

A brief comparison of some JavaScript templating engines on a short template: 6 header tags, and 10 list items.

Preface: many comparisons made here are conceptually incompatible, this test is more for 'fun' than anything. At a high level these libs could all be thought of as 'templating engines', but many of them serve disparate purposes. This test somewhat like comparing the speed of Java, C, Javascript, Erlang and FORTRAN.

Note: When adding a new test, please ensure that your test returns the same HTML string (or equivalent DOM fragment) as the others. Note2: @AndrewF why did you delete the latest two changes? Any comments?
