ucar.ma2.ArrayStructure
Concrete implementation of Array specialized for floats. Data storage is with 1D java array of floats. issues: what should we do if a conversion loses accuracy? nothing ? Exception ? @see Array @author caron

        String[] vals = sdata.split(" ");
        double took =  .001 * .001 * .001 * (System.nanoTime() - start);

        Array data = Array.makeArray(DataType.DOUBLE, vals);
