Detailed Description

template<class GEOMETRIC_ELEMENT>
class oomph::BackupMeshForProjection< GEOMETRIC_ELEMENT >

//////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////////////// Class that makes backup (via a deep copy) of a mesh, keeping alive enough information to allow the solution that is currently stored on the mesh to be projected onto another mesh sometime in the future (when the original mesh may already have been deleted). This is mainly useful for the projection of additional nodal values (such as Lagrange multipliers) created by FaceElements. ASSUMPTION: All fields in the element are represented by isoparametric Lagrange interpolation between the nodal values. Any fields that do not fall into this category will not be copied across correctly and if you're unlucky the code may die...).

Project the solution that was present in the original mesh and from which this backup mesh was created onto the mesh pointed to by new_mesh_pt. Note that elements in the new mesh do not have to be projectable. The original mesh may by now have been deleted.
