Addition (+)

!!! notes "+" Add two instance of [[FEVariable_]].

!!! note "" A quadrature variable can be added to only a quadrature variable, unless one of the variable is constant.

!!! note "" A nodal variable can be added to only a nodal variable, unless one of the variable is a constant.

!!! note "" The rank of obj1 and obj2 should be the same, if none of the obj1 and obj2 are scalars.

!!! note "" A Scalar FEVariable can be added to a Vector and Matrix FEVariable.
