* 'master' of github.com:PyMVPA/PyMVPA:
  BF: guard attempting to store shape for empty arrays with buggy hdf5
  BF: if storing nested complex __reduce__'able objects -- __new__ instance first
  ENH: do not fail logging if passed arguments fail to stringpolate
  NF: MVPA_DEBUG_PDB to fall into debugger upon exception
  BF: store is_objarray and shape, provide target container for objarrays
  BF: correctly reconstruct nested dicts and lists with nasty self-references
  BF: no -e for elderly awk, and probably not needed
  disable start_easy for error of which even google doesn't have a clue
  BF: fi not done!
  BF: removing removed cmdline examples from Makefile targets
  BF: query_pymvpa.sh removing dumping of info into a file (logic was removed)
  NF: "make coveragecmdline" (and change to .travis.yml) to run cmdline tools under coverage
  NF: tools/coverage-bin/pymvpa2 - a simple wrapper to run bin/pymvpa2 with coverage
  ENH: make use of MVPA_TESTS_QUICK in fmri_analyses.sh for reasonable runtime
  NF: tutorial_data downscaled spatially to 25mm
  BF: script to generate spatiall downsampled tutorial_data for testing
  BF: cmd_searchlight -- with scattering and fa mask specified should operate on those in fa mask
  DOC: just minor typos
  ENH: fmri_analyses.sh -- allow to be ran on downscaled dataset
