"""
Decorator to reduce boilerplate of rendering view to template.
Requires that the view returns a dictionary of context as opposed
to the rendered template. Decorator can be called with or without
keyword arguments. If called without arguments there is no need to
add a method call using @render_to(), it will work as @render_to.
Examples:
@render_to(template_name='home.html')
def home(request)
...
@render_to
def home(request)
...
