> Instantiating some of the Thrift classes is painful.  Consider building a {{Table}} object,
which requires a {{StorageDescriptor}}, which requires a {{SerDeInfo}} and a list of {{FieldInfo}}.
 All that is really necessary for a Table in the most simple case is a name, a database, and
some columns.  But currently creating even a simple Table requires 20+ lines of code.  This
is particularly painful in tests.  
> I propose to add a set of builders.  These will come with reasonable defaults to minimize
the boilerplate code.  They will also include simple methods for common operations (like adding
columns, or a parameter) without requiring the user to create all the sub-objects (like {{StorageDescriptor}}).
