ENH: support arbitrary structs
RF: use faster isfield
OPT: use faster generation of spaces
OPT: do not check dataset when stacking or slicing
Merge branch 'master' into _meeg
NF: provide values in output
Merge branch 'master' into _meeg
ENH: set voxel dimensions properly even for oblique volumes
BK+ENH+BF+ACK: properly deal with NIFTI orientations, even if the volume is oblique. Thanks to #Jens Schwarzbach# and #Mohamed Tawfik# for bringing up this issue
NF: support for re-orientation of fmri volumes
NF: support for getting the orientation of an fmri volume
BF+ACK: provide proper error message for old dataset structs. Thanks to #Jens Schwarzbach# for bringing this up
RF: change fmri synthetic dataset to have origin inside the volume
BIG+BK+RF: update fmri dataset handling, with support for changing the orientations, proper dealing with nifti files without changing header information, and minor changes to BV functionality
ENH: better detection for AFNI being present
BF: show proper build message when using -force option
Merge branch 'master' into _orient
NF: conversion of xform
BF: fix eroneous behaviour when not all predictions are set when using crossvalidation.
RF: combine two exceptions into one when searchlight fails
