use swig-templates module

[fatihky]

since swig module is unmaintained, there is a maintained fork exists.

@fatihky thanks for the PR.

Can you change this so both options are available and the user can decide which one they want to use? This will be similar to jade and pug that try to require in pug and if that fails, then requires in then-pug.

Then you can include the swig-templates link in the readme after the unmaintained swig link.

Hey @doowb, I made changes prior to your comment. Could you check them out if these ok?

[doowb]

@fatihky this looks great, thanks!
