> In order to make the grammar more consistent, to reflect the spec changes=
 after CMIS 0.5 and to simplify processing the AST the following changes sh=
ould be performed:
> - Make nodes in grammar tree for AND, OR and NOT operators
> - remove imaginary tokens BIN_OP and UN_OP as they do not provide value
> - rename imaginary token BIN_OP_ANY to EQ_ANY (EQ is now the only allowed=
 operator)
> - use two different imaginary tokens SEL_LIST and IN_LIST for list of lit=
erals in SELECT and WHERE part (these are different things)
> - Introduce new imaginary tokens IN_ANY, NOT_IN_ANY for <quantified  comp=
arison predicate> as this is a separate operator requiring its own processi=
