Implementation methods for mapper objects
A bru_mapper sub-class implementation must provide an
ibm_matrix() method. If the model size 'n' and definition
values 'values' are stored in the object itself, default methods are
available (see Details). Otherwise the
ibm_n() and ibm_values() methods also need to be provided.

The default ibm_n() method returns a non-null element 'n' from the
mapper object, and gives an error if it doesn't exist.
The default ibm_values() method returns a non-null element
'values' from the mapper object, and seq_len(ibm_n(mapper)) if
it doesn't exist.
The default ibm_amatrix() method calls the ibm_amatrix element function
of the object if it exists.
The default ibm_valid_input() method returns an all-TRUE logical vector.
ibm_amatrix for bru_mapper_multi accepts a list with
named entries, or a list with unnamed but ordered elements.
The names must match the sub-mappers, see names.bru_mapper_multi().
Each list element should take a format accepted by the corresponding
sub-mapper. In case each element is a vector, the input can be given as a
data.frame with named columns, a matrix with named columns, or a matrix
with unnamed but ordered columns.
ibm_valid_input for bru_mapper_multi accepts a list with
named entries, or a list with unnamed but ordered elements.
The names must match the sub-mappers, see names.bru_mapper_multi().
Each list element should take a format accepted by the corresponding
sub-mapper. In case each element is a vector, the input can be given as a
data.frame with named columns, a matrix with named columns, or a matrix
with unnamed but ordered columns.
[-indexing a bru_mapper_multi extracts a subset
bru_mapper_multi object (for drop FALSE) or an individual sub-mapper
(for drop TRUE, and i identifies a single element)
The names() method for bru_mapper_multi returns the names from the
sub-mappers list
