Set zsh (zshell) colors for ls command

Catalina uses zsh (zshell) instead of the old bash or (even older) sh. To set colorized display of files and directories when using the ls command, modify ~/.zprofile or ~/.zshrc with something like:

export CLICOLOR=1
export LSCOLORS=CxFxExDxBxegedabagaced

When you run the ls command, it will display the files colorized according to their type like this:

Setting CLICOLOR to 1 enables colorization. Setting LSCOLORS to the string shown sets the colors for the different file types.
