Hi all,

> improved z-spread calculation and removed redundant dirty-price based interface

Sure it was redundant, but:
1) it's convenient;
2) it's inexpensive to maintain;
3) as it's defined as a set of free-standing functions, we're not adding
excess baggage to a class interface.
In short, I'd restore the dirty-price functions since I don't see any
disadvantage in them.

Previously, I had kept the yield calculations in Bond because I felt
that they were used as much as, say, theoretical-price calculations, so
they deserved to be methods in Bond.  On the other hand, I see that it's
convenient to have the calculations in a separate file.  How about we
make a compromise and keep the methods in Bond forwarding to the
external functions?
