Run C++ nupic.core tests through new gtest interface

[utensil]

Fixes #1298 .

This PR is NOT ready to merge until:

• Integrate Google Test and port all tests in testeverything nupic.core-legacy#179 is merged
• .nupic_modules is updated accordingly

[coveralls]

Coverage increased (+0.03%) when pulling 3cf7b44 on utensil:1298-gtest into 1461a5a on numenta:master.

Assuming this commit sha is in numenta/nupic.core, the line above needs to be reverted to point to the right github fork.

[breznak]

I think @utensil is aware of it, he mentions this in TODO.

[oxtopus]

This PR shouldn't require a reference to an outside fork in .nupic_modules, even if meant to be temporary. If these PRs need to be coordinated, let's get the nupic.core changes pushed to a branch on numenta/nupic.core so that at least the SHA is valid (even if not on master).

[utensil]

Yeah, this is similar to the situation of the pip-installable PR. But adding a branch to numenta:nupic.core can only be done by a owner.

[breznak]

@utensil @rhyolight @oxtopus let's re-trigger build here to see OSX , regarding the discussion in numenta/nupic.core-legacy#179

[utensil]

Triggered. Let's see what happens.

Coverage remained the same when pulling 6387751 on utensil:1298-gtest into d466667 on numenta:master.

@utensil I manually reset the status with the url http://issues.numenta.org:8081/validate?sha=d607a54d24779f170b88ea67487997193e98916b&postStatus=1&repo=numenta/nupic

[utensil]

Updating the SHA1 caused this PR to be affected by the transformation to C++ 11, which is in progress and failing at #1264 . This is why the latest build is dark on all OS and compilers.

Blocked by #1264.

As the C++11 commits in nupic.core are reverted, this is not necessarily blocked by #1264 anymore.

[oxtopus]

This one's 👍 once .nupic_modules is updated to the right fork.

[utensil]

I was confused by the git history at first and eventually figure this out.

There was an attempt by oxtopus to merge my branch at #1408 but somehow failed the Mac build. And then oxtopus used a better method to link gtest: instead of linking gest built in nupic.core, build gtest in nupic itself again, which would avoid implicit dependency on nupic.core internal build structure. This work is at #1409 and already merged into master while I was sleeping 😴

But there was one piese missing in #1409, the cpp_unit_tests is still referring to testeverything instead of the new name unit_tests.

So after I resolved conflicts with numenta:mater, this PR has become a one line PR...

[utensil]

Closing this and go to #1413
