Detailed Description

Header for small strain, isotropic, linear elasticity kernels.

   Strong form:    -div(sigma(u))

   The constitutive model is given in terms of Lame parameters,
   sigma(u) = lambda*div(u)I + 2*mu*sym(grad(u)).
   The weak form implemented is (suppressing integral)

   Weak form :     lambda*div(u)*div(v) + 2*mu*sym(grad(u))*sym(grad(v))

   DATA LAYOUT ASSUMPTIONS :
   Finite element space - Ordering::byNODES
   Finite element basis - ElementDofOrdering::NATIVE
   Quadrature functions - QVectorLayout::byNODES
   All elements in "fespace" are the same.
