Update to Solr 5.x

[markrmiller]

I've been working on this, but have a couple loose ends to tie up still.

Hi Mark,

I am trying to run your solr-map-reduce-example on mac and having some problems/questions on the run-example.sh script. Couldn't fully understand from run-example.sh script how exactly you are trying to launch solr. In the curl/collection api command while creating collection you have mentioned numshards=1 but I see you are starting solr on two ports with numshards=2. Would appreciate if you can provide some more details on setup that I can try to run thru this solr-map-reduce-example.
