utiml 0.1.0

First release of utiml:

• Classification methods: Binary Relevance (BR); BR+; Classifier Chains; ConTRolled Label correlation exploitation (CTRL); Dependent Binary Relevance (DBR); Ensemble of Binary Relevance (EBR); Ensemble of Classifier Chains (ECC); Meta-Binary Relevance (MBR or 2BR); Nested Stacking (NS); Pruned and Confident Stacking Approach (Prudent); and, Recursive Dependent Binary Relevance (RDBR)
• Evaluation methods: Create a multi-label confusion matrix and multi-label measures
• Pre-process utilities: fill sparse data; normalize data; remove attributes; remove labels; remove skewness labels; remove unique attributes; remove unlabeled instances; and, replace nominal attributes
• Sampling methods: Create subsets of multi-label dataset; create holdout and k-fold partitions; and, stratification methods
• Threshold methods: Fixed threshold; MCUT; PCUT; RCUT; SCUT; and, subset correction
• Synthetic dataset: toyml
