Detailed Description
template<int dim, int nstate, typename real>
class PHiLiP::Physics::Burgers< dim, nstate, real >
Burger's equation with nonlinear advective term and linear diffusive term. Derived from PhysicsBase.
State variable: \( u \)
Convective flux \( \mathbf{F}_{conv} = 0.5u^2 \)
Dissipative flux \( \mathbf{F}_{diss} = -\boldsymbol\nabla u \)
Source term \( s(\mathbf{x}) \)
Equation:
\[ \boldsymbol{\nabla} \cdot ( \mathbf{F}_{conv}( u ) + \mathbf{F}_{diss}( u, \boldsymbol{\nabla}(u) ) = s(\mathbf{x}) \]

If diffusion is present, assign Dirichlet boundary condition.
Using Neumann boundary conditions might need to modify the functional in order to obtain the optimal 2p convergence of the functional error
