Installing and using universal-ctags instead of exuberant-ctags

It is simple, as in the universal-ctags docs:

git clone https://github.com/universal-ctags/ctags.git
cd ctags
./autogen.sh 
./configure
make
sudo make install

I'm on Ubuntu 19.04, and for me I can use either:

sudo apt install universal-ctags

or

sudo snap install universal-ctags

The snap tracks a newer version of universal-ctags (snap=2019-10, apt=2018-12), but the snap is currently missing a few important features due to the default isolation of snaps. (For example, reading from config files at ~/.ctags.d/*.ctags.) I intend to fix the snap in the near future.
