/**
 * This package contains the classes that make up the SQM tree nodes.
 * <p/>
 * NOTE: the choice to prefix all SQM tree node class names with <b>Sqm</b> was
 * made to help make consumers easier to write - consumers are likely to
 * have classes with the same purpose in their AST (e.g. the notion of a
 * "From".  But if both projects define a class named {@code From} then the
 * consumer would have to fully qualify one reference to distinguish.
 * That makes for overly long code.  Prefixing the names of classes helps
 * alleviate that problem.
