serialize DataFrame

[tshort]

Built-in serialization works for the following example:

d = DataFrame(quote
    a = [1:5]
    b = letters[11:15]
end)
f = open("t.jbin", "w")
serialize(f, d)
close(f)
f = open("t.jbin")
dd = deserialize(f)()
close(f)
dd | dump

A nicer wrapper might be nice.

Are there cases where this does not work? Can we close this?

As far as wrappers go, I think save makes sense, but is there a way we could use load for loading it?

Also, I think I saw that they discussed using .jld as the suffix for such things.

I don't know of cases where this doesn't work (I haven't tested it much). I think we can close this.

For wrappers, save sounds good. I don't think we can use load as that's used for reading in Julia scripts (along with include and require).

.jld also rings a bell. Maybe ping the mailing list, or if you or someone writes a wrapper, submit it to core because it's not JuliaData specific.

OK, I included your code using save and load_df (for now at least): e4b7b21
