Make install script that will materialize standard templates

Make a gradle target that will install default templates in `views/_fields/` and `views/templates/_fields` with a starting point for further development of tags.

Start by locating the Gradle build configuration and inspecting the existing views/_fields/ and views/templates/_fields directories. Determine how a Gradle target can install the default templates and what starter tag structure those files should provide. Done means the target materializes templates in both stated locations for further tag development.
