Merge #984

984: Implimented Soluion 1 and solution 2 for issue_734 r=philberty a=mvvsmk

Fixes #734 
Done :
- [x]  Remove iterate_params function
- [x] Create new get_params function

Solution 1
1) Created a new get_params function which returns the parameters.
2) Changed the references of the iterate_params to use get_params.

Solution 2
1) Added get_params2 which returns `std::vector<TyTy::BaseType*>`
2) Changed the references of the iterate_params to use get_params.

Status :  
Currently I have implemented the first solution.
