Create a pipe mapper, where mappers is a list of mappers,
and the evaluated output of each mapper is handed as the state to the next
mapper.
The input format for the ibm_eval and ibm_jacobian methods is
a list of inputs, one for each mapper.

Other mappers:
bm_aggregate(),
bm_collect(),
bm_const(),
bm_factor(),
bm_fm_mesh_1d,
bm_fmesher(),
bm_harmonics(),
bm_index(),
bm_linear(),
bm_logsumexp(),
bm_marginal(),
bm_matrix(),
bm_mesh_B(),
bm_multi(),
bm_repeat(),
bm_scale(),
bm_shift(),
bm_sum(),
bm_taylor(),
bru_get_mapper(),
bru_mapper()
Other specific bm_pipe method implementations:
ibm_eval(),
ibm_eval2(),
ibm_jacobian(),
ibm_n(),
ibm_n_output(),
ibm_simplify(),
ibm_values()
Examples
m <- bm_pipe(list(
scale = bm_scale(),
shift = bm_shift()
))
ibm_eval2(m, input = list(scale = 2, shift = 1:4), state = 1:4)
