Constructor Details

#initialize(nodes, keys, column_size) ⇒ Body

Creates a new Body instance.

nodes - A Hash representing all columns. The key is the

Symbol column's header and the value is an Array
full of column's values.

keys - An Array of Symbol header’s column. Why passing the

column's names while they are contained in `nodes`?
This is because we want the header's names in that
particular order given by `keys`, we can't rely on
the order of the *Hash* `nodes`.

column_size - The Fixnum size of a column. TODO I think this

parameter isn't needed.
