Release DateMath B0.2.0

Major feature upgrade with implementation of strongly typed (generic) accrual periods and an accrual schedule object. With these you can model your own accrual periods (with their own underlying and/or fixings) and the accrual schedule will manage the adjustment, daycount fraction and payment calculations for you.

Generified holiday calendars to simplify their use with subclasses of Period.

Note: If you have created your own concrete implementation of HolidayCalendarFactory then you will need to update it to support the new generics interface of the abstract HolidayCalendarFactory. Further details can be found here.
