" File: multiple_cursors.vim
" Author: Terry Ma
" Description: Emulate Sublime Text's multi selection feature 
" Potential Features:
" - Create a blinking cursor effect? Good place to do it would be instead of
"   waiting for user input, cycle through the highlight
" - Integrate with the status line? Maybe show a special multicursor mode?
" - Support mouse? Ctrl/Cmd click to set cursor?
