gVenn 0.99.0

New Features

• Initial release of the gVenn package.
• Introduced a workflow for overlap analysis:
  • computeOverlaps() computes intersections across multiple sets of GRanges or gene lists, returning counts and membership categories.
  • extractOverlaps() retrieves the actual elements (regions or genes) that belong to each overlap group for downstream analysis.
  • exportOverlaps() exports overlap groups to an Excel file, creating one sheet per group and converting GRanges to data frames when needed.
• Added visualization functions:
  • plotVenn() to draw proportional Venn diagrams based on overlaps between genomic regions (e.g., ChIP-seq peaks).
  • plotUpSet() to visualize complex overlaps with an UpSet plot.
• Added saveViz() to export visualizations to PDF, PNG, or SVG formats, with optional date tagging in filenames.
