A new draft for introduction.Rmd Vignettes
dendextend_options.R - moved `dendextend_options` functions to it.
A new "warn" dendextend_options parameter. logical (FALSE). Should warning be issued?
`get_branches_attr` - change "warning" to "warn", and it now works with is.dendrogram, and no longer changes the class of something which is not a dendrogram.
ALL `warn` paramteres are no set to dendextend_options("warn") (which is FALSE)
Update .Rd docs, now that ALL `warn` paramteres are set to dendextend_options("warn") (which is FALSE)
untangle_step_rotate_2side` - print_times is now dendextend_options("warn"),
Include dendextend_options("warn", TRUE) in tests.
`color_branches` - now handles flat trees more gracefully. (returns them as they are)
`cutree.dendrogram` - now replaces NA values with 0L
