Broken build.  Just over road some retain release calls for debugging.
Initial periods and the ., pattern seem to be causing an overrelease of ,.  Not sure why.
Turns out punctuation was never being retained initially and the ., pattern was causing a crash.
Fixed a bug where the convention that PNodeVectors need not respect list structure was forgotten.  it was causing plurals to fail if one plural had more than one word in it.
Merge branch 'feature/value-memory-management' into feature/PNode-memory-managment
Added some logging.  Eliminated one (of many) leaks of PNodes.
