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

             Summary: [Python] Add utility functions (or a richer type 
hierachy) for checking whether data type instances are members of various type 
classes
                 Key: ARROW-1576
                 URL: https://issues.apache.org/jira/browse/ARROW-1576
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Python
            Reporter: Wes McKinney
             Fix For: 0.8.0


E.g. {{is_integer}}, {{is_unsigned_integer}}. This could be implemented similar 
to NumPy, too ({{isinstance(t, pa.FloatingPoint)}} or something)
