			<documentation>An object describing an Atterberg Limits test procedure. The Atterberg limits are a basic measure of the nature of a fine-grained
                soil. Depending on the water content of the soil, it may appear in four states:
                solid, semi-solid, plastic and liquid. In each state the consistency and behavior of
                a soil is different and thus so are its engineering properties. Thus, the boundary
                between each state can be defined based on a change in the soil's behavior. The
                Atterberg limits can be used to distinguish between silt and clay, and it can
                distinguish between different types of silts and clays.</documentation>
