/**
 * Represents a file that will never exist on disk - a placeholder backing file for untitled Documents. NO ONE
 * other than DocumentManager should create instances of InMemoryFile. It is valid to test for one (`instanceof
 * InMemoryFile`), but it's better to check `doc.isUntitled` where possible.
 *
 * Attempts to read/write an InMemoryFile will always fail, and exists() always yields false. InMemoryFile.fullPath
 * is just a placeholder, and should not be displayed anywhere in the UI; fullPath IS guaranteed to be unique, however.
 *
 * An InMemoryFile is not added to the filesystem index, so if you ask the the filesystem anything about this
 * object, it won't know what you're talking about (`filesystem.getFileForPath(someInMemFile.fullPath)` will not
 * return someInMemFile).
