> The following patterns:
> {code}
> g.V().or(has("age",gt(20)), has("age",lt(32)))
> g.V().and(or(has("age",gt(20)), has("age",lt(32))),has("age",neq(23))
> {code}
> should be re-written by {{InlineFilterStrategy}} as:
> {code}
> g.V().has("age",gt(20).or(lt(32)))
> g.V().has("age",gt(20).or(lt(32)).and(neq(23)))
> {code}
> This would then make it easier for provider strategies to fold the predicate into graph/vertex-centric push down predicates accordingly.
> Note that {{InlineFilterStep}} already has the code to flatten {{AndSteps}}. Thus, during its recursion, it would do the following rewrites to get to the final form.
> {code}
> g.V().and(or(has("age",gt(20)), has("age",lt(32))),has("age",neq(23))
> g.V().or(has("age",gt(20)), has("age",lt(32))).has("age",neq(23))
> g.V().has("age",gt(20).or(lt(32))).has("age",neq(23))
> g.V().has("age",gt(20).or(lt(32)).and(neq(23)))
> {code}
