Change SimpleUnitOfMeasure restriction on property baseConversionRatio

If defined with someValuesFrom xsd:integer, Protege considers that it is an object property. Possibly a Protege bug, but in any case the cardinality restriction is semantically more accurate: the proxy member cannot have more than one sequence value.

Change restriction from someValuesFrom to cardinality. In the former case, Protege interprets baseConversionRatio as an object property. Could be a Protege bug, but in any case the cardinality restriction is more accurate.
