Helpful parent class for row objects. Also used as the default row class by Table instances. Provides an __init__() method that accepts keyword arguments from which the object's attributes are initialized.

Example:

>>> x = Table.RowType(a = 0.0, b = "test", c = True)
>>> x.a
0.0
>>> x.b
'test'
>>> x.c
True

Also provides .__getstate__() and .__setstate__() methods to allow row objects to be pickled (otherwise, because they all use __slots__ to reduce their memory footprint, they aren't pickleable).
