Merge branch 'master' of https://github.com/PyMVPA/PyMVPA
BF: change the unit test concerning earlier change of volsurf mapping from nodes to voxels
BF: mixed up the voxel positions - fixed that
BF: ensure h5{save,load} are imported in unit test
Merge branch 'master' of https://github.com/PyMVPA/PyMVPA
RF: rewrote node to voxel mapping code to allow for other algorithms
DOC: more documentation for vol surf mapping
PL: whitespace fixes
BF: proper from_any from filename
BF: use the new name for NIML support ("niml" instead of "niml_dset")
ENH: proper error message when query engine not trained
NF: surface-based voxel selection supports a new argument, "minimal_mapping", that when set to True returns a mapping from nodes to sets of voxels so that each voxel is associated with at most a single node
RF+ENH: refactored minimal voxel selection yielding significant speedup
RF: remove unnessary computation of voxel count image
ENH: be more lenient in checking voxel selection results
NF+BK: store meta information in voxel selection results. This may break using existing voxel selection results (but actually it should not)
PL: whitespace fixes
RF+BK: use "voxel_node_mapping" rather than "use_minimal_mapping" as argument for voxel selection
DOC: removed commented-out code
ENH: use number of voxels per node with two decimals
