I realized yesterday that this problem will happen for everyone with nupic
already checked out when they update. The right command to fix it (cleaner
than `rm -rf nta`) would be:
git clean -dfx
This will remove all untracked files within the repository, including the
"nta" directory. Running the build after that will install the submodule
properly.
