I'm trying to be more consistent and precise when naming functions and classes, so I've decided that within the context of the code, certain words should have more specific meanings than they usually have:

• path should be understood to mean web path, i.e. part of a URL accessible by a web browser
  • a fragument is the part of a path that comes after the page's base path -- i.e. it may contain arguments
• spec should be understood to mean file spec, i.e. the path (relative or absolute) to a file accessible by code on the server
• rows are sets of field data stored in a database
• fields are in-memory storage of an individual row
