+inheritance the basic building blocks of general algebraic structures.
+Specific implementations of algebraic structure traits are left to other
+crates.  Higher-level traits for specialized domains of algebra (like linear
+algebra) are also provided and will prove useful for applications that include
+code that is generic with regard to the algebraic entity types.")
