Instead of implementing our own templating system, we abuse org-capture's templating system. We add 2 additional properties: - :head: a starting template that goes at the beginning of the file. - :file-name: a string that expands to the file name The templates are customizable at `org-roam-capture-templates` and `org-roam-ref-capture-templates`.
