Hyunsik Choi updated TAJO-344:
------------------------------

    Attachment: TAJO-344.patch

I've attached the patch. This patch modifies SQL parser, algebraic expression, logical plan
in order to support sign numeric values. In addition, this patch removes comments of unit
tests including minus constant values.

I verified 'mvn clean install'.
