Changes to params dictionary.  Valid values for 'fixed' are 'fixed' 'float' or an integer.  True and False are no longer acceptable.  Now mutli-ROI curve fitting seems to work!

New LMA function in fit_module allows us to simultaneously fit parameters to the data in several ROIs that share that parameter.  This is not yet fully tested.  More comments have been added to ba_class.  The __all__ variable has been added to osprai_one to assist the automatic documentation.

The new module osprai_one provides access to the important functions in all of the other modules.  Documentation has been started with osprai_one.html.

Added clma(), a constrained LMA fitting function.  We can now set a lower and upper bound for fitting.  Be sure that the initial estimate is between, not at, the bounds.  It transforms the parameters using x1 = ((b-a)*tanh(x0)+b+a)/2 for the interval (a,b).

Introduction of the fit_module.  This provides ordinary Levenberg-Marquart curvefitting.  The user can choose which model parameters are fixed and which are allowed to float.  Next, we can add a constrained version.
