Re: [Quantlib-dev] Period class... some minor updates...

Hi Nando,

I agree with you that the Period class is much more flexible and powerful.
I can see this within the new Schedule constructor(s).

Currently I am in need of the new frequency types and thus have integrated 
this into my framework, however if, as you say, there is a bigger picture of 
using the Period class everywhere, then I'm happy just to keep this local 
until such time that the Period class is replicated everywhere.

In actual fact, I use the Frequency enum type as a placeholder for the user 
to easily identify a period of time, but internally I convert this to the 
Period type and then call the new Schedule constructor.

By the way, the new (work in progress) schedule class doesn't work with the 
daily frequency type (the constructor that takes the boolean endOfMonth 
parameter). It generates repeated daily dates...

Toy out.
