Added _getSurveyRecordFor method to Survey View.
This method is used by the Take view to get the right SurveyRecord for the current request. Subclassed Views that want to fetch their records in another way can override this method.
TEMPLATE NAMESPACESTemplates are placed in a "namespace" subdirectory in the templates directory,since the templates directory will be added to the Django templates searchpath. This allows other packages to extend existing templates without "hiding"the original template. For example, a template in another Melange applicationcan extend a template in the SoC framework like this: {% extends 'soc/some_existing_template.html' %}without "hiding" the some_existing_template.html for other uses, even if thederived template is also named some_existing_template.html.So, please do not put any templates in this soc/templates directory, but onlyplace them in the soc/templates/soc "namespace" subdirectory.Different Melange applications should also follow this pattern, to promotesharing of templates between applications as well. For exmample, the GSoCMelange application should place its templates in gsoc/templates/gsoc.MODEL/VIEW TEMPLATE NAMINGView templates are usually named some_view.html for a corresponding someView()function and SomeViewForm form class. Since SomeView is likely to be a commonView name for multiple Models, Model-specific templates should be placed insoc/<model>/<view> sub-directories.
