fix qlo / cmsmarket
fix argument type
make alpha guess a bit smarter by adapting it to the level of beta,
lower upper bound for nu guess, remove transformation of guess which
is wrong here (it rather seems to belong to the code commented out above)
fix computation of row index when populating the result matrix,
add inspector for swap lengths,
make exception messages more expressive
add calibration to a termstructure of betas,
use transformed variables in optimization instead of constraints
update the parameter guess only if a parameter guess quote changes and not on each notification, because
otherwise e.g. a calibrated beta structure is lost on each such update,
add option for backward flat SABR parameters, deduce default acceptance level from max error,
allow for recalibration with beta termstructure
add backward flat / linear interpolation
add new file to makefile
simplify formula
update the cube after parameter guess update
avoid shadowing of outer loop variable, use preincrement in inner loop
add parametric beta termstructure, reformatting
fix beta0, remove leftover fail message
make some inspectors virtual (in order to make the corresponding inspectors work in classes like spreaded smile section)
add inspector for reference date
add inspectors
use previously computed result
add example for gaussian 1d models
fix member and parameter types
allow swap engine for float float swap instrument
