Detailed Description

The node data structure.

This data structure allows the implementation of a lisp like s-expression.

lineno It is used to store the line number of the input file to which the stored data refers to.
type It indicates the kind of node we are dealing with. I.e. if the node is CONS like, or a leaf, and in this case which kind of leaf (NUMBER, ATOM, ...).
left It's the left branch of the s-expression.
right It's the left branch of the s-expression.
link It's a pointer used in the internal hash.
