Detailed Description

Mutator to enforce constrained evolution after every time step.

Togglable option in input file via option tag defined in Ccz4::fd::Tags. If constrained_evolution is true, enforce the unit determinant constraint on the conformal spatial metric and traceless constraint on the ATilde
