Methods upper and lower

Description

Accesor and replacement methods for the lower and upper attributes of objects of class FLModel-class. These are stored as part of the structure inside the initial slot. This slot contains a function to be used to provide initial values to any of the fitting method (e.g. fmle).

The values in lower and upper are only used if the method selected for optim is able to make use of them, like for example "L-BFGS-B", which is the default for fmle.

The exact location of this information could be changed (i.e. a separate slot might be created), so code accessing it is encouraged to use these accesor methods.
