SelectScalarExpression.Expression-Eigenschaft

Gets or sets a select expression that can be any expression, if this is non-null then this select expression is a regular expression. At present this AST class expresses either an expression or a wildcard. Because a SelectExpressions can do so much more, we may want to go to a derivation approach, where this class would be a base -- or there may be another more elegant approach. For now, this is a basic design to support SELECT * FROM foo.
