first draft of subcortical activation
renamed example, added docstring, created a high level function in source_space.py, added epoch details instead of loading from file
merged cortical and subortical source spaces in example. had to comment out ValueErrors in source_estimate.py
implemented import order changes. removed import nibabel (no longer used). implemented pyflakes and pep8 flags.
removed references to outdated mne.fiff
Merge branch 'gsoc-subcortical' of github.com:leggitta/mne-python into gsoc-subcortical
Merge branch 'master' of git://github.com/mne-tools/mne-python into gsoc-subcortical
cropped epoch data after calculating noise covariance
example: removed fixed orientation from forward operator, supports writing/reading forward operator, broke code into sections. source_space: simplified indexing using numpy.where
Crashed on import mne

Merge branch 'master' of git://github.com/mne-tools/mne-python into gsoc-subcortical
reinstated warnings for source spaces
updated example, added function in source_space to append volume to surface sources
getting upstream changes

Merge branch 'master' of git://github.com/mne-tools/mne-python into gsoc-subcortical
added downsampling to subcortical volume
added support to read/write segmentation name for discrete source spaces
removed example, focusing on mixed source space implementation
added tests for mixed source spaces
pep8 corrections
