Possible 0.7 / 1.0 issues

Lots of warnings so it is a bit hard to parse these. Many are repeats but the chain seems to start with MAT.

WARNING: importing deprecated binding Base.Complex64 into MAT_HDF5.

And then, more:

followed by lots of SparseMatrixCSC warnings:

WARNING: Base.SparseMatrixCSC is deprecated, run `using SparseArrays` to load sparse array functionality

I suspect this arises from this call to load .MAT files in my extract_data function:

function extract_data(matfname::String)
    # read the data
    df = matread(matfname)
                 .... more stuff
    return ...
end
