Create customer view

[jbillcliffe]

As a site user/admin user, I want to be able to view customer details and easily view actions I can take

• Customer screen to be shown after selecting them from a list of customers.
• Show key customer contact details on main screen.
• Button options, clearly labelled as to their function, to provide actions.

• Screen is loaded from the customers_list after clicking on the magnifying glass.
• It displays the personal information of the customer.
• Buttons initially used, moved to a changing nav-bar on the side to free up more screen space.
