[x] option to put in version control / clone prior to creation
[x] option for yarn install
[x] switch from yarn to npm since that's the default
[x] #2014
[x] check for existing folder
[x] switch from ejs to twig syntax so we normalize across php version better and don't have two syntaxes within the same project (oi!)
[x] drop templates for site, defer to what's coming from haxcms-nodejs (might want to leverage CLI methodology to "post" data on command line in order to generate any outcome; longer term better way to go)
[x] detect context of site vs multisite
[x] Ask if single (default) or mutlsite
[x] Menu of options (all on by default). multi-select instead of the lots of questions Y/N so that default everything is on.
