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

[~xhochy] I added this to the 0.2 release. This is an overdue API cleanup

> Currently the builder classes all expect to be passed a {{shared_ptr<DataType>}} -- for the primitive types (boolean, numbers, strings, etc.) it would be simpler to default to a common value rather than requiring that you obtain an instance yourself from someplace (e.g. {{arrow::uint8()}} as in the WIP patch for ARROW-373)
