Protected config parser against an empty string.
Fixed MCMC

from something that made no sense to something that hopefully works.
FitModel::defineParameter returns the index assigned to the newly created parameter.
Fix bug in AbsBinning::dump.

Merge remote branch 'mblomqvist/Create_bicubic_interpolator_class' into Add_bicubic_interpolator
Merge Michael's pull request with new BicubicInterpolator class and accompanying likelybicubic test
program, based on existing tricubic interpolator stuff. Might want to re-organize this with a common
2D interpolation base class and bilinear and midpoint implementations. Could also move imengine
2D interpolation integrals into this framework sometime.
Merge branch 'master' into Fix_MCMC
Add a scale parameter for priors.
For Gauss, (min,max) spans scale*sigma. For box, sigma of Gaussian rolloff outside (min,max) is scale*(max-min).
New config syntax is (min,max;scale).
Original (min,max) syntax is still supported, with defaults 1 (gauss) and 0.01 (box).
Fix bug in FitParameter printToStream.
Add optional scale parameter for priors.
Merge remote branch 'slosar/Fix_MCMC' into MCMC_updates
Restore the nll return value of setRandomParameters, even though MCMC no longer needs it.
Fix whitespace and remove debug printout.
