rquery: Relational Query Generator for Data Manipulation

A query generator based on Edgar F. Codd's relational algebra and operator names (plus experience using 'SQL' at big data scale). The design represents an attempt to make 'SQL' more teachable by denoting composition a sequential pipeline notation instead of nested queries or functions. Package features include: data processing trees or pipelines as observable objects (able to report both columns produced and columns used), optimized 'SQL' generation as an explicit user visible modeling step, and convenience methods for applying query trees to in-memory 'data.frame's.
