There was a problem hiding this comment.
This is a bad merge. I moved most of these files to the Annotations group in #5110. You should move MGLAnnotationContainerView.h/.m to that group but otherwise omit this diff.

Looks good, other than the bad merge in the project file. |
Add a container view to hold annotations. This gets around a performance issue with `UIView:addSubview:` where adding views is N^2. It helps annotation views avoid cutting into callout views when the annotation views are transformed to be "flat".

Fixes #5140
Fixes #5089
Adds a new UIView subclass to contain MGLAnnotationView instances and an API for helping to manage the addition of new annotations. To mitigate known performance issues with
UIView:addSubview:, this batches up the addition of subviews to the container before adding the container itself to the view hierarchy. The organization of the views in the separate container also naturally avoids the "piercing" issue seen before between annotations and callouts.
