Renamed class CodeToExpression to ExpressionPreparer. Changed parse logic in of meta expressions: - In quoting, meta expressions are returning as they are to be processed within ExpressionPreparer - In ExpressionPreparer, the body (an expression) of meta expressions are prepared and investigated as to whether they result in an ExpressionAST or not-   - If not resulting in an ExpressionAST, then an implicit conversion is attempted to be generated.     - E.g., if result type is String, then the body is wrapped within a "new StringLiteralAST(...the result of body...)" expression.
