Helper methods to work with Camera

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`public final class`	`Utils.AspectRatioComparator`	Compares Camera.Size according to aspect ratio it represents regards to matching to some perfect desired target aspect ratio. For example: `Collections.min(sizes, AspectRatioComparator(targetAspect))` will return the size whose aspect ratio is closest to target.
