edited line search and started with quadratic stuff
Merge branch 'master' of https://github.com/factorie/factorie
Span.end: Fix definition to match comment.  Now is index after last
token of span; (was index of last token of span).  Fixed internal usages
for new definition.  WARNING:  If you use Span.end (including
TokenSpan.end) directly, you should fix your code.
Span.value: Now immutable; (was mutable, tracking future changes to
the Span).

BP: fix typo
fix test failures
app.nlp.ner.NER3: actually setting to the maximizer at test time
BP-ish: actually calling .setToMaximize when using BP.inferChainMax, as it's no longer the default behavior
la: adding code to initialize dense tensors randomly
Changing Spans so that they don't automatically add themselves to a ChainWithSpansVar.
new spans: fixing type issue
new spans: removing This type, which is no longer necessary in Span and SpanVar, and drastically simplifies what the code looks like
