More than one Model

[shaileshiitm]

We need option to add as many models' variable as user define.

Are you asking for more than one model (like title of issue says), or more than one model variable (like contents says).

Either way there will be more than one model variable. Should all be plotted on all output plots? And metrics calculated comparing each model variable to obs?

Actually, we may have more than one model as well as situation where we have one model for more than one variable such as flow, PET, SM etc.
