cdlatex has 4 main functionalities:
+ Math and environments snippets: I've disabled these in favor of
yasnippet when using :editor snippets by just unbinding the TAB in
cdlatex's keymap
+ Auto insertion of closing delimiters: disabled in favor of smartparens
+ Fast insertion for some macros: `a becomes \alpha. Kept as-is
+ Fast accent insertion: a'~ becomes \tilde{a}. Kept as-is
I also updated the docs, and added a section explaining how to re-enable
cdlatex's snippets despite having yasnippet.
