Daru::MultiIndex#initialize

names and levels should be of same size. If size of Array `name` is less
or greater than size of array `levels` then it raises `SizeError`.
If user don't want to put name for particular level then user must put
empty string in that index of Array `name`.
For example there is multi_index of 3 levels and user don't want to name
level 0, then do mulit_index.name = ['', 'level1_name1', 'level2_name']
