class GinqAstOptimizer
extends GinqAstBaseVisitor

Optimize the execution plan of GINQ through transforming AST.

Note:The optimizer only optimizes the AST for inner/left joins for now, e.g.

    from n1 in nums1
    innerjoin n2 in nums2 on n1 == n2
    where n1 > 1 && n2 <= 3
    select n1, n2
 

    from n1 in (
      from alias86329782 in nums1
      where alias86329782 > 1
      select alias86329782
    )
    innerjoin n2 in (
      from alias23802906 in nums2
      where alias23802906 <= 3
      select alias23802906
    ) on n1 == n2
    select n1, n2
