Predict

------------------

Fixed
~~~~~
- Catch type error in semantic file computation.
- Several printing statements improved.
- Bug when computing 1D shape features: one feature value was missed,
so number of labels and values did not match.

Changed
~~~~~~~
- Histogram features min, max, range and IQR are the only ones computed
on raw data. Others are computed on histogram to be more robust to outliers.
- LBP features now extracted using the histogram features, in accordance
to other filter features.
- Gabor features now extracted using the histogram features, in accordance
to other filter features.

------------------

Fixed
~~~~~
- Explicitly mentioned PyWavelets version requirement to solve bug.

------------------

Fixed
~~~~~
- Bug in shape features when using mask with multiple blobs.
- Printing commands in texture features now properly outlined.

------------------
Added
~~~~~
- Error when config file cannot be found.
- Support for 1D images.

Fixed
~~~~~
- Catch error when image slice is too small for GLCM, give warning
and skip respective slice.
- For large images, GLSZM gave an error. Increased bin width until error
resolves.

------------------

Fixed
~~~~~
- Compatibility issue with PyRadiomics => 2.2.0: edited requirements.

------------------

Fixed
~~~~~
- Check in patient features to assign value "unknown" when DICOM tag is not
present.
- Bug in GLCM and GLCMMS texture features: label name did not include the
angle, but the distance twice.
- CalcFeatures used to look at the shape parameter in the
config['ImageFeatures']: fixed to look at histogram instead.
- Major bug in image helper that took omitted the last slice of the mask for
the shape feature computation.
- Proper python gitignore
- Updated travis.yml.
