genearlize slope limiting to meshes
Promote the slope limiting part from ScalarEq.rhs!
for FVElement
s to src/mesh.jl
for wider adoption.
This PR also implements integration for Mesh1d{<:FVElements}
, although its far from being general yet.
Both features should be adapted slowly into the other projects.
So far we only updated ScalarEq
and there only the muscl
method.
To also migrate the fv_central
method I will need to think more about that schemes integrates with general slope limiters.
