A knowledge structure is considered a knowledge space if it includes one
state for the empty set *{}*, one state for the full set of domain
problems *Q*, and a state for the union of any two knowledge states
(i.e., the closure under union).

`kstructure_is_kspace`

takes an arbitrary knowledge structure and
tests for its space property.

`kspace`

takes an arbitrary knowledge structure or base and
returns the corresponding knowledge space.

For `kstructure_is_kspace`

a logical value.

For `kspace`

an **R** object of class `kspace`

where each
subset represents one knowledge state of the knowledge space.
