It takes a variable of type multi_contact_frame wich describe
the contact situation (master and slave contact boundaries,
self-contact detection or not, and a few parameter).
For each slave boundary (and also master boundaries if self-contact
is asked) a multiplier variable should be defined.

/** Adds a large sliding contact with friction brick to the model.
This brick is able to deal with auto-contact, contact between
several deformable bodies and contact with rigid obstacles.
The condition is applied on the variable `varname_u` on the
boundary corresponding to `region`. `dataname_r` is the augmentation
parameter of the augmented Lagrangian. `dataname_friction_coeff`
is the friction coefficient. `mim` is an integration method on the
boundary. `varname_u` is the variable on which the contact condition
will be prescribed (should be of displacement type). `multname` is
a multiplier defined on the boundary which will represent the contact
force. If no additional boundary or rigid
obstacle is added, only auto-contact will be detected. Use
`add_boundary_to_large_sliding_contact_brick` and
`add_rigid_obstacle_to_large_sliding_contact_brick` to add contact
boundaries and rigid obstacles.
