Operates like a matrix (for multiplication) with a large number of inhibition
values and a small number of excitation values. Notionally, for each
dimension at the target layer, there is a small number of matching dimensions
at the source layer, from which it receives excitation rather than inhibition.
parameter default_value excitation 1 inhibition 0

Print a human-readable list of excitation mappings; each row represents a dimensions on the target layer representation, and lists the “matching” dimension numbers on the source layer representation.
