better support for integer parameters in fit

Description

For models such as pearl necklace which have an integer number of pearls, some bumps fitters will fail. LM and newton in particular will fail; nelder-mead and DE won't fail, but may not select the best integer; dream should work fine, though not as efficiently as it could if it knew it were working with integer parameters.

Other models such as the n-shell model need to introduce extra parameters with each additional shell. These are not supported by any fitter.
