concatenation between vector and dataframe

[genya0407]

Daru::DataFrame cannot be concatenated with Daru::Vector. The inverse is also true.

Pandas can do it.

Daru can concatenate dataframes with a different set of vectors. Use #to_df on anything that might be a vector and you should be able to concatenate them.

@v0dro - Makes me think we might want to litter many of the dataframe methods with #to_df at the beginning to force anything that might be a vector into a single-vector dataframe.

That can be a quick fix for now. A more long term solution would be implementing those methods natively for Vector.

@gnirets Thanks, I'll concat with that solution 😄
