Detailed Description

Bullet bond vs Libor swap.

for mechanics of par asset swap and market asset swap, refer to "Introduction to Asset Swap", Lehman Brothers European Fixed Income Research - January 2000, D. O'Kane

Warning:: bondCleanPrice must be the (forward) price at the floatSchedule start date

Bug:: fair prices are not calculated correctly when using indexed coupons.
