#121 Excel function qlFixedRateBondHelper is deprecated

[Wasi]

Problem:
The Excel function qlFixedRateBondHelper in QuantlibXL Version 1.0b3
produces an error messsage: "qlFixedRateBondHelper - Boost assertion
failed: px != 0" which is due to an uninitialized bond parameter in the
BondHelper constructor.

Solution:
The function qlfixedratebondhelper is deprecated and
will or should be removed in the coming version. The new function is qlBondHelper.

One can create a fixed rate bond using qlFixedRateBond and forward this
object to qlBondHelper. This should be the same financial construct.

Yes, there was a bug, but not sure why you claim it's deprecated. This should be fixed on the master branch now. Not sure whether the fix was in time for v1.4's release.

I applied the fix on R01040x-branch, so it went out in the 1.4 release. The fix was included in the merge from R01040x-branch to master. Many thanks.
