Dendritica is a collection of programs for relating dendritic geometry and signal propagation. The programs are based on those used for the simulations described in: Vetter, P., Roth, A. & Hausser, M. (2001) For reprint requests and additional information please contact Dr. M. Hausser, email address: m.hausser@ucl.ac.uk

COMMENT
iterator for traversing all the descendants of the currently accessed section

section subtree_traverse("statement")

executes statement for section and every descendant of section.
Just before the statement is executed the currently accessed section is set.
