causality: Accessor function for the 'causality' information in a mRMRe.Filter and mRMRe.Network object.
Description
The causality data is compute using the co-information lattice algorithm on each V-structure (feature, target, feature). Given that this procedure
is computed for each pair of features, the minimum result is kept. A negative score indicates putative causality of the feature to the target.
Usage
## S3 method for class 'mRMRe.Filter':

## S3 method for class 'mRMRe.Network':
