7b22ee8ecb Add support of CAST(expression AS datatype(length)) 
CAST(expression AS datatype(length)) construction is a part of
ANSI SQL-92 standard. So we have to support it.

daf8fe7a45 Changing Grammar to extend CASE WHEN statement: 
- allow multiple WHEN statements
- allow for syntax like `CASE x WHEN 1 THEN 2 WHEN 3 THEN 4 ELSE 5 END`
NOTE: This changes also the way the CASE operator is stored:
- CASE [expr] exprList [ELSE expr2] END
- exprList holds each of the WHEN statements with:
  expr := WHEN, expr2 := THEN

Added also tests in test/select_tests.cpp
and adapted the existing one to reflect the new storage

88ffe4822b Many updates to grammar including support for arrays, ilike, natural joins with no predicates... (#49) 
* Got ISNULL working

* Allow function calls with no arguments

* Added no-else cases and arrays

* Added more operations including ilike, concat

* Added optional all to set operations and fixed natural join

* Ran astyle

* Used the appropriate star expression

Instead of using a ColumnRef with star literal.

* NULL expressions now returns true isLiteral

* Fixed structure for no-else case clauses

* Fixed up grammar conflicts
