• Minor fix for the umbrella header.
• Template fix for non-int types of Index_ in aggregate_across_cells().
• Check that the row indices for each gene set are not out of range in aggregate_across_genes().
• Bugfix to aggregate_across_genes() to zero user-supplied buffers.

v0.2.1

• Added the aggregate_across_genes() function to aggregate expression values across genes, possibly with weights.

v0.2.0

• Added combine_factors_unused() to combine factors while reporting unused combinations.
• Added the clean_factor() utility to remove unused levels from a factor.
• Streamlined combine_factors() by not reporting the counts, as these can be obtained externally.
