Bug fix-- fiber values for image data are computed
AFQ_get now is agnostic to an underscore before clean when looking for a cleaned fiber group
updated the call to AFQ_get(afq,fiber group clean) to make look at the number of subjects with cleaned fiber tracts before returning a path
updated how the number of subjects is computed by AFQ_plot and the line type used for the plot
