TroubleShooting
---------------
    The script will remap keys ([{'"}]) <BS>, 
    If auto pairs cannot work, use :imap ( to check if the map is corrected.
    The correct map should be <C-R>=AutoPairsInsert("\(")<CR>
    Or the plugin conflict with some other plugins.
    use command :call AutoPairsInit() to remap the keys.


* How to insert parens purely

    There are 3 ways

    1. use Ctrl-V ) to insert paren without trigger the plugin.

    2. use Alt-P to turn off the plugin.

    3. use DEL or <C-O>x to delete the character insert by plugin.
