Pug to html runs the currently opened file through the
pug Plugin and displays
the output html.
pug2html.compileOptions: the options that are passed to pug for compilation
pug2html.compileOptionsPath: a path to a json or js file that exports the compile options
If the file at
compileOptionsPath exports a function, than that function is called in order to get the compile options.
In this case the file name is passed as an argument to the function.
