UnitConverterconvert(u + v) == convert(u) + convert(v) and
convert(r * u) == r * convert(u).
For linear converters the following property always hold:[code]
y1 = c1.convert(x1);
y2 = c2.convert(x2);
then y1*y2 = c1.concatenate(c2).convert(x1*x2)[/code]isLinear in class UnitConvertertrue if this converter is linear;
false otherwise.
