Use <leader>c to insert a bibtex reference in your text. By default it
is a pandoc reference (@bibref), but it can be changed to latex style
(\cite(bibref)). <leader>CM inserts a pretty-printed reference to the
selected work, using markdown styling. If you want to insert a citation
while writing, use @@ from insertmode to insert the bibref instead.
The settings add two commands: :CiteRef and :CitePretty which call the
respective functions. You can pass any amount of .bibtex libraries to
the commands and they will be available to fuzzy search through.
