Batch runner redux

[tpike3]

Summary of Changes:

I recommend after anticipated further modifications we do a version push. My timing on this is to give you time to review and then discuss at next Dev Session 6 August.

BatchRunnerMP

• removed pathos (unnecessary as unorderedmap in pathos is same as multiprocessing)
• refactored so compatible with Windows, Mac and Linux OS

Batchrunner

• add two functions and updated run functions so users can call model datacollectors
• get_collector_model: returns dictionary of dataframes for datacollector model reporters
• get collector_agents: returns dictionary of dataframes for datacollector agent reporters
  (key for dictionaries is unique parameter variation with iteration number)

DataCollector

• expanded to allow more collection types to be passed in model reporter (agents are handled internally so I did not think it was needed). This was necessary because lambda cannot be used at the model level for multiprocessing

  key_name: class attribute
  key_name: function (e.g schedule.get_agent_count)
  key_name: lambda function
  key_name: [function, [param1, param2]]
  

Tutorial

• Updated tutorial to include to different batchrunner collection examples (1) From batchrunner directly (2) From datacollector in model stored in dictionary

Closing to fix lack of codecov report

[Corvince]

Sorry for not reviewing this already. Is there a new PR coming?

Also: There seems to be quite a lot unrelated file changes. Could you somehow separate the batchrunner changes from the rest?

Also also: Thank you so much already for doing this. I know this must have been quite a lot of work and it is very essential to fix batchrunner!

@Corvince Thanks! As you pointed out there really is two areas of fixes - (1) Batchrunner the which includes includes changes to datacollection because of their interdependencies, a batchrunnerMP test module, and documentation update. (2) The example folders, these were all failing to run because of import path issues. Which I thought was weird so I may be misunderstanding something, but I got them running to make sure all the travis checks pass, but then Travis did not run and I did not get a codecov report. I am trying figure out why, but I will try to seperate them and get the travis check and codecov working for cleaner pull requests.

@Corvince I found the Travis test (thanks to your conversation with @rht). I will fix the failures and that should get the codecov report and then I will do the pull request again
