Test setup teardown

[d2fong]

• add setup/teardown functions that run before the tests and after all the tests
  • these functions right now populate/depopulate the test database
• create testing config
  • hooks up the setup/teardown functions
  • other params aim to reduce the total time taken when running tests
• remove /help/ from the build tooling script

This is the first step for #20 #24.

Also, can you elaborate on what you would like for #20 related to that catmaid testing file? I am not sure I know exactly what you are talking about.

Awesome! Looking great. To answer your question regarding issue #20, I simply meant that it would optimal for the tests to work independent of the current data files. So if the data files change, the tests would still work perfectly. The CATMAID link is just one example of such a setup. Before each test, the test suite first populates the database with the minimally required data needed to perform the test. So the tests are completely independent of data.
