Usage: settheme.sh [arguments]

	-bg, --background	changes the background between light and dark for n/vim
	-c, --colorscheme	shows fzf menu containing installed colorschemes to Choose
				colorscheme from it.
				This sets colorscheme for \$TERMINAL and .Xresources as well which
				in turn also changes theme for polybar and other tools too
	--gen	generate file with installed themes of n/vim to use with other scripts
Note: if no argument is provided then it'll be default to changing colorscheme.

Currently supported for n/vim, alacritty, termite, Xresources, polybar(with xresources), dunst and rofi

You have to compile dmenu yourself for now after runnning this script, work in progress
