Scripts that operate on meet-data shouldn't search outside of meet-data
Our tests and scripts (like standardize-names.csv) walk the directory tree looking for files named "entries.csv" and "meet.csv".
Sometimes these files occur in build directories. Recently I named a git branch "entries.csv" and then builds started failing because it was reading a branch header file of the same name in my .git
directory.
We should change it so that every time we're doing directory walking, if there's a file named "meet-data" in the current directory, then we just constrain ourselves to walking through "meet-data" (ignoring folders named "build" and "fetch").
