create Quick Start Guide

[sreichl]

• a "hello world" toy example to download MrBiomics and run instantly.
• minimal but real bio data
  • minimal runtime (5-30s)
  • minimal code/config complexity
  • minimal output complexity (1 pretty plot)
• Biologically meaningful example:
  • dea_limma: Bulk RNA-seq analysis with volcano plot / heatmap as output
  • enrichment_analysis: multiple related gene lists with meaningful clustered bubble plot as output
    • gene lists from RNAseq recipe ie hematopoietic signatures or
    • just take celltype cluster DEA lists from some scRNAseq data
    • either call the mystery sets and choose a database that clearly shows cell types / the answer
    • in case of COPD fgsea example use: REACTOME_EXTRACELLULAR_MATRIX_ORGANIZATION
• This should be at the top of the wiki features "Start here with the Quick Start" or similar
• Should include everything from installation to plot
