Constructor with Vector or Numo::NArray

[heronshoes]

I want to construct DataFrames with Vectors or Numo Arrays.

vector = RedAmber::Vector.new([1, 2 ,3])
RedAmber::DataFrame.new(x: vector)

numo_array = Numo::DFloat(3).rand_norm
RedAmber::DataFrame.new(x: numo_narray)

I will try to create an issue from this. #104

Finally resolved in 0.2.3 (#137).
