Save cell geometric attributes

• Adds tdy_output_cell_geo_attributes <filename> to save cell geometric attributes
• Adds tdy_read_cell_geo_attributes <filename> to read cell geometric attributes

Are we providing these options to bypass the geometry calculation because it's so expensive? I can see doing this for testing purposes while we're optimizing these kinds of calculations, but I'd rather spend energy trying to make geometry cheaper to calculate than providing options which allow users to get themselves into trouble (think about using older geometry files with meshes that have been recently modified).

Yes and this might be a temporary fix to reduce initialization cost.

Yes.

Just computing geometry once is expensive? It should be about the same cost as a residual evaluation. Is it more?

Thanks,

My goal here is to reduce the initialization time for the purpose of quickly debugging the code.
