Snowball search vignette

[yjunechoe]

Compiling oa_snowball() doc enhancement ideas across issues:

FAQ:

• Count discrepancies: Number of edges from oa_snowball doesn't match cited_by_count #178
• Maybe rehash some general discussion about large query results

Using filters:

• Search by doi: Feature Request: Do snowball search also from DOI and not only from works id #259
• Search by orcid: Snowball search by author(s) #30
• Passing params to backward/forward searches Is it possible to sample only a subset of works when using oa_snowball ? #279

Analysis - {tidygraph}/{ggraph}:

• Related to the oa_snowball and ggraph tidygraph code  #62
• Another oa_snowball vignette #119
• I'd personally like to see more data wrangling with {tidygraph} (ex: filter(oa_input | centrality_degree(mode = "all") > 1) filters input papers and connections with 2 or more edges shared between the inputs)

Misc.

• Flattening with snowball2df(): Flattened 1-table snowball output #23

@trangdata Can I close #119 in favor of tracking the vignette discussion here? Also please feel free to add if I missed anything!
