===========
*) Bumped major version to 1
*) Fixed code causing deprecation warnings
*) Fixed a bug in a test when using Python 3
*) Widened what is accepted as a generator by paycheck
(In particular, now any type can specify how to generate
random data for itself by providing a
make_new_random_generator method.)
*) Added choice generators for generating random selections
from a list of values.
*) Now in Python 3 an exception of type Exception is raised in
the paycheck handler rather than a new exception of the
type originally thrown.
