66688f7199 Adjust Table Join Types 
Consolidate LeftOuter/Left and RightOuter/Right as they are
by definition the same.
Similar consolidate FullOuter/Outer/Full ... with Outer (as in the
parser) not part of standard, but "full" missing. Allowing all three.

This commit potentially breaks other programs as kJoinLeftOuter and kJoinRightOuter
are eliminated

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

bcb5fe5e82 Enable compilation on clang++ also 
‘uint’ is only available on Linux. Other than this, there seems to be
no other dependency on the compiler.
