Feature 1: Capture video feed from external camera

[ElliotAOram]

Add functionality to capture the output from a camera. This should work with both the internal webcam and an external webcam (The test should be carried out using the internal webcam as tests will not normally include external webcams at this point in time)

• Entry tasks:
  • [ ] Create video processing application
  • [ ] Create unit test for video processing application
• Design feature:
  • [ ] Consult overall model and decide if change is required
• Build by feature:
  • [ ] Write tests for camera feed feature
  • [ ] Write code to pass tests
  • [ ] Refactor where required

[ElliotAOram]

Simple enough that design does not need to be updated at this point

[ElliotAOram]

No refactoring required for this issue
