`gsl_fit`

struct that contains three other structs, which contain the data, the parameters and the model functions.
All the parameters must be part of a single array, so as a result they are seperated from the model function to which they belong. Which parameters belong to which model function? That is stored in the function struct as the index. To get the parameters for any function `i`

;

gsl_fit tmp; unsigned int i; unsigned int start_index = tmp->func[i].idx; unsigned int end_index = tmp->func[i].idx + tmp->func[i].num - 1; tmp->para.par[start_index] //first parameter tmp->para.par[end_index] //last parameter

The only place where it is needed to keep tack of which paramter is which is inside the user-supplied function that uses it, i.e. `d->func.fun`
