Deletion of Eigenclass model

Comment: to Ruby_(programming_language)#Semantics. Eignenclass is a real concept in the Ruby language community, it is a reasonable search term and we should have something on it at WP.  But this article seems to be a  for a massive expansion of the concept beyond what is found in reliable sources. A complete cutdown of this article to just the shim class idea could work, although making it more than a definition may prove a challenge given the meager sources I found. Merging just the definition to Ruby_(programming_language)#Semantics and redirecting seems the best solution at this point
