Cooccur

Create an R function called `cooccurrence` that builds co-occurrence networks from various data formats. It should support six different input formats and allow users to specify eight different similarity measures and eight scaling methods. The function must return a tidy edge data frame with columns for `from`, `to`, `weight`, and `count`. I also want it to seamlessly convert the results to `igraph`, `tidygraph`, `cograph`, and `Nestimate` objects. Please include examples demonstrating its use with delimited fields and multi-column delimited data.
