compare_SMCs: Compare all strata from different stratifications
In slw287r/yapsa: Yet Another Package for Signature Analysis

Compare all strata from different orthogonal stratification axes, i.e. othogonal SMCs by cosine similarity of signature exposures. First calls

compare_SMCs(
  in_stratification_lists_list,
  in_signatures_ind_df,
  output_path,
  in_nrect = 5,
  in_attribute = ""
)

`in_stratification_lists_list`	List of lists with entries from different (orthogonal) stratification axes or SMCs
`in_signatures_ind_df`	A data frame containing meta information about the signatures
`output_path`	Path to directory where the results, especially the figure produced by `corrplot` is going to be stored.
`in_nrect`	Number of clusters in the clustering procedure provided by `corrplot`
`in_attribute`	Additional string for the file name where the figure produced by `corrplot` is going to be stored.
