Modules
module	les_model
	Implements les_model_t.

Functions/Subroutines
subroutine	les_model::les_model_init_base (this, dofmap, coef, nut_name, delta_type)
	LES model factory. Both constructs and initializes the object.
subroutine	les_model::les_model_free_base (this)
	Destructor for the les_model_t (base) class.
subroutine	les_model::les_model_compute_delta (this)
	Compute the LES lengthscale. For each GLL point, we take the distance between its neighbours in all 3 directions divided by 2 with the exception of face nodes, where only one neighbour exists. To form the lengthscale the distances along 3 directions are multiplied, and a cubic root is extracted from the result. This roughly corresponds to a cubic root of the cell volume in FVM computations.
