Rolling average dynamic weight updating

Fxed Hausdorff implementation. The successive erosions were not applied to the eroded diff variable, but to the original diff variable (hence, no successive erosion was done at all)

Made HausdorffDistanceErosion channel sentinel.

Updated call to DataGeneratorManager

Generalized the DataGenerator to accept two lists of input and output (wrt network) labels to fetch from the dataset files.

Implemented NCC loss function

Quick cleanup of unused imports. Specially when importing TF

Added verbose option to save_nifti

Merge remote-tracking branch 'origin/WeaklySupervised' into WeaklySupervised

Train only on segmentation data

Removed NCC, training only on Hausdorff and DICE

Merge pull request #1 from jpdefrutosSINTEF/HausdorffConstantIndependent

Made HausdorffDistance independent of the package file constants

Missing a parenthesis when getting the normalizing factor

Added __init__.py file

Removed NCC, training only on Hausdorff and DICE

Missing extension

Renamed model
