""" An example which demonstrates overriding `layout_constraints`.
This example shows how one can override `layout_constraints` method from
enaml syntax to generate custom constraints using procedural code. This
can be useful for complex layout scenarios where generating constraints
from a single expression would be difficult or impossible.
