//# This file defines classes derived from TableExprNode representing
//# the data type and operator in a table expression.
//#
//# Data types Bool, Int64, Double, DComplex and String are used.
//# Char, uChar, Short, uShort, Int, and uInt are converted to Int64,
//# Float to Double, and Complex to DComplex.
//# Binary operators +, -, *, /, ==, >=, >, <, <= and != are recognized.
//# Also &&, ||, parentheses and unary +, - and ! are recognized.
