A fancy 'are you sure' style shell prompt
fancyprompt take at least two args, the prompt message and produces an 'are you
sure' style prompt with a timeout of 10 sec and option to cancel with 'c'.
The first arg is always the message as a string (accepts \n \t etc). And the
remaining args are function names that are called depending on the result.
The best way to create a multiline string template variable which has variables within it and contains double quotes.
IMPORTANT: The variable inserts must be assigned before the string template is declared and before it's used! EACH TIME THE INSERTS ARE MODIFIED, THE TEMPLATE MUST BE RE-RECLARED! For this reason it's sometimes handy to put the template def inside a function so you can call/re-call it before using it.
