 *
 *  Contains the functions to be assigned as boundary conditions, in the file boundaryConditions.hpp . The functions
 *  can depend on time and space, while they can take in input an ID specifying one of the three principal axis
 *  if the functions to assign is vectorial and the boundary condition is of type \c Full \c.
