The ASTextContainer class defines a region in which text is laid out.

ASTextLayout class uses one or more ASTextContainer objects to generate layouts.

A ASTextContainer defines rectangular regions (`size` and `insets`) or

nonrectangular shapes (`path`), and you can define exclusion paths inside the

text container's bounding rectangle so that text flows around the exclusion
|

path as it is laid out.
