The @byrow example in the README doesn't work

[xiaodaigh]

using DataFrames
using DataFramesMeta
df = DataFrame(A = 1:3, B = [2, 1, 2])
df2 = @byrow df begin
    @newcol colX::Array{Float64}
    @newcol colY::Array{Union{Int,Missing}}
    :colX = :B == 2 ? pi * :A : :B
    if :A > 1
        :colY = :A * :B
    else
        :colY = Missing
    end
end

Yes, we should

1. Make a patch release with the new @byrow naming. It makes sense to do this now that @cols in @byrow works.
2. Use actual documentation instead of a readme so that we can have separate documentation for master vs. release branch.

OK

Closing this, it was fixed when we added real documentation in #208.
