At the beginning of each Exercise file, there is a header in YAML format.
There are two lines with a separator (---) only, and the header is between them.
The required keys are type (string) and name (string). All the others are ExT-dependent (Exercise Type dependent).
There is ExT-dependent content after the second separator.
