Query lookups using operators

This class emulates query lookups to behave as numeric operators. Inspired by SQLAlchemy. User.objects.filter( X('username') == 'diverman' ) User.objects.filter( X('username') != 'diverman' ) User.objects.filter( X('pk') > 10 ) User.objects.filter( X('pk') >= 10 ) User.objects.filter( X('pk') < 10 ) User.objects.filter( X('pk') <= 10 ) User.objects.filter( X('username') % 'iverma' ) User.objects.filter( X('username') << 'diver' ) User.objects.filter( X('username') >> 'man' ) User.objects.filter( X('pk') | (1, 2, 3) )

URL models

You can use `UrlModel` to provide URL functionality to any instance of any model and any language (language support can be removed from this). Each model must have own view method, that returns HttpResponse. I was inspired by Flatpages. It is useful for small sites and static pages. `class Page(UrlModel): text = models.TextField() def view(self, request) # do something here return HttpResponse(...)`
