Comment on posInc > 1 (stopwords); issue #13
TagLL needs to be public AND define a public API to allow implementations of TagClusterReducer

* changed class from default to public
* added public getter for properties needed by TagClusterReducer implementations
* changed removeLL() method from default to public as TagClusterReducer need to be able to reduce tags
(cherry picked from commit bacac03)
Ported from v1.2: Add 'skipAltTokens' (vs error) and added initialization of top level init args as invariants.
(cherry picked from commit 038e98b)
removed deprecated subTags param (since replaced by overlaps)
Issue #13 added ignoreStopwords with smart default

ignoreStopwords: A boolean flag that causes stopwords (or any condition causing positions to skip like >255 char words) to be ignored as if it wasn't there. Otherwise, the behavior is to treat them as breaks in tagging on the presumption your indexed text-analysis configuration doesn't have a StopWordFilter. By default the indexed analysis chain is checked for the presence of a StopWordFilter and if found then ignoreStopWords is true if unspecified. You probably shouldn't have a StopWordFilter configured and probably won't need to set this param either.

Tests pass on Solr 4.6.0 too.
