[bikeshed] VideoStream, VideoCapture, Camera, and more... names

[funnbot]

Currently

• tracker::VideoCapture matches opencv naming, a class which is used to get frames of video from cameras.
• cfg::Camera parameters used by VideoCapture to open and read a camera.
• cfg::VideoStream contains a cfg::Camera, plus any parameters required to process the frames from cameras.
• cfg::CameraCalib calibration for a camera.
• tracker::CapturedFrame a single frame and the timestamp it was captured at.

Definitions for some real pointless discussion

• Video - visual media product featuring moving images, a sequence of pictures.
• Capture - take possession of
• Video Capture - google: mostly capture cards
• Camera - a device for capturing a photographic image or recording a video.
• Stream - to send forth or discharge in a stream
• Video Stream - google: tv streaming services
• Image - array of pixels
• to image - instead of capture?
• Frame - a single image in a sequence of pictures

I'm looking for alternatives, or thoughts on current names.
