parallel construction, indexing and querying of de Bruijn graphs

 Bifrost is a command-line tool for sequencing that features a broad
 range of functions, such as indexing, editing, and querying the graph,
 and includes a graph coloring method that maps each k-mer of the graph
 to the genomes it occurs in.
 .
  * Build, index, color and query the compacted de Bruijn graph
  * No need to build the uncompacted de Bruijn graph
  * Reads or assembled genomes as input
  * Output graph in GFA (can be visualized with Bandage), FASTA or binary
  * Graph cleaning: short tip clipping, etc.
  * Multi-threaded
  * No parameters to estimate with other tools
  * Exact or approximate k-mer search of queries
