Subject: [PATCH] make: create a new file

- Creates a templates and a notes directory.
- Creates a default template use to create new files. It contains a
  minimal frontmatter with the creation date and an ID.
- Adds the *new* recipe which creates a new file in the notes directory,
  based on the default template, replacing the creation date and ID
  variables with according values.
- Updates the README file with the new recipe.
- Fixes #9.
