simple comment out plugin
`u comment line(s)
`o uncomment line(s)
`i comment line(s) while keep coding
for trying new code line
but if you want code line(s) keep intact
( default : same as `k, that is, to the upper )
`k comment out to the upper
`j comment out to the below
Visual blocking or numbering(buffer count) in normal mode will work as expected.
Currently for python, Makefile, snippet, cpp, javascript, ruby, sh matlab, tex, txt, anonymous, c, html
You might feel free to add other comment string and filetype by modifying s:CommentStringMap and sure you can change key map to your favorite.
