+BiGpairSEQ creates a [weighted bipartite graph](https://en.wikipedia.org/wiki/Bipartite_graph) representing the sample plate.
 The distinct TCRA and TCRB sequences form the two sets of vertices. Every TCRA/TCRB pair that share a well
 are connected by an edge, with the edge weight set to the number of wells in which both sequences appear.
 (Sequences present in *all* wells are filtered out prior to creating the graph, as there is no signal in their occupancy pattern.)

   * ~~*No, this won't work, because BiGpairSEQ simulations alter the underlying graph based on filtering constraints. Changes would cascade with multiple experiments.*~~
   * Might have figured out a way to do it, by taking edges out and then putting them back into the graph. This may actually be possible.
   * It is possible, though the modifications to the graph incur their own performance penalties. Need testing to see which option is best.
