[Feature] Online Unitary Event Analysis

[ojoenlanuca]

This pull request introduces an online version of the Unitary Event Analysis (UEA). It is related to the pull request #405, because it provides another online batched statistic. These pull requests could be reviewed jointly, but also separately, depending on what will be more efficient in terms of the overall time needed for the reviews.

Like the other online batched measures in #405, the online version of the UEA is implemented as a class, which stores the necessary intermediate results within class-attributes and updates them with the aid of the 'update_uea()' class-method. To perform such an update-step, several helper-methods are used to manage the spike data and to pre-process it in the same manner as the standard/offline UEA it does.

The 'concurrent_test_runner_for_uea.py' module is optional. It executes all test-functions of 'TestOnlineUnitaryEventAnalysis' unittest.TestCase, which is located in 'test_online.py', in a concurrent manner to reduce run-time. It uses the third-party package 'concurrencytest', which is yet not part of the 'elephant'-requirements.

Task List

• [x] decide whether this pull request will be reviewd jointly or separately from #405

Hey @ojoenlanuca, I suggest to proceed with this PR in the following way:

1. review code
2. create PR on branch INM-6:feature/online_measures (this branch was recently updated to match the current state of elephant), see also PR #405
3. merge into master
