A learning path is considered a *gradation* if each state in a
learning path differs from its predecessor and/or successor state by
a single item/notion.

`lpath_is_gradation`

takes an arbitrary list of learning paths and
tests for their gradation property.

A `list`

of logical values where each element represents one learning path.
