-----------------------------------------------------------------

[~wesm], [~apitrou]  For our purposes we need to define a custom type and use 
arrow CSV reader to parse it. Unfortunately, there is no way to use custom 
types with CSV reader right now, because of type dispatch when choosing an 
appropriate column builder. 

I'm not sure how architecturally it could be solved, maybe custom ColumnBuilder 
is a case.
