(ba) The aim of this function is to precise the analysis made by easyp3cut applying it to a precise nom object. Using the composition of easyp3trouve(easyp3cut(chain),nom) gives a result directly usable (for well introduced users of rebastaba). The check is made on the validity of node names, on the validity of the numerical constants. Completed information about the \$typ=2 (nodes and variables) is returned.
output of easyp3cut
nom object where node/variable names will be investigated
when a node is involved, all its variables are considered as involved. If A is a node repeated three times, then "A" implies "A", "A" and "A" as variables but "A" implies node "A" and only variable "A".
A list comprising \$node: the internal number (i with respect to nom)
of the nodes involved,
\$vari: the internal number (k with respect to nom) of the variables involved,
