After resolving conflict within group, implemented project-level template base.html. Started to adapt dashboard templates to new base.html.

Implemented edit widget user page. Created UserUpdateView in views.py that also accepts UserForm into the attribute form_class. Configured url for the said view in urls.py and created widgetuser-edit.html

Implemented add new widget user page. Firstly, created forms.py and wrote class UserForm so that css styling can be applied to the form. Forms.py was imported into views.py so that UserForm may be passed into the form_class attribute of the newly created CreateView, UserCreateView. This view was then linked to widgetuser-add.html, which was created afterwards. The appropriate path was added to urls.py.
