Setups should be run for every yaml "doc"

Previously, setups were run once per yaml file.  But a yaml file
may have multiple "docs" (separated by --- ), and setup needs to
be reun before each test.

This commit preparses the entire yaml file and saves the setup if
it exists, which is then run before each test case.
