the failed approach on theming.
checking in for reference.
this almost works, but is not seamless. requirement is theme should be
changable on request to request basis, and while it can almost do it,
[request to request basis theme selector not done yet, but it can be
imagined how it would be done [update the views to handle ?theme= query
parameter]], it can not dynamically apply the themes to the template
enhiritence flow.
so all themes must define a version for each template, including the
ones i am cooking, containing different {% extends %} at top. FAIL.
next approach write gitology template loader
gitology.d.utils.ThemedTemplateLoader.
