Mapping from pyradiomics features to IBSI

[fedorov]

IBSI assigned codes to the features described in the document starting from v7 (https://arxiv.org/abs/1612.07003). Instead of maintaining a separate document with the mapping (as was done in this example), we agreed it makes sense to include this mapping using some kind of predetermined decorator in the documentation of the individual features.

Sorry to bug you guys, but was this ever implemented? Also how would this decorator be accessed by the end-user (other than looking in the code itself)?
