Resample with PeriodIndex should allow third option

[changhiskhan]

Suppose I have:

prng = period_range('1/1/1999', freq='M', periods=3)
s = Series(np.random.randn(len(prng)), prng)

s.resample('D') should by default go from 1/1/1999 to 3/31/1999
as opposed to 1/31/1999 - 3/31/1999 ('e') or 1/1/1999-3/1/1999 ('s')

I don't see what's wrong. There are two options here, no?:

s.resample('D', convention='start')
s.resample('D', convention='end')

[changhiskhan]

I was thinking the 3 monthly periods should cover January 1st to March 31st so resampling to daily period frequency should also cover the same.
convention='start' covers Jan 1st to Mar 1st
convention='end' covers Jan 31st to Mar 31st

Ah, I see. A third kind of convention. Let's push this to the next release, but shouldn't be too hard
