OutlineParser
OutlineParser parses top-level declarations in source
to find declared classes, ignoring their bodies (which must only have balanced braces). This is used to map class names to defining sources.

did not consume any source for its construction. In this case, don't assign a span yet, but wait for its span to be determined by setChildSpans

is not missing before it. This is done as follows: If the next token S is indented relative to the current region, and the end of body
is followed by a new line and another statement, check that that other statement is indented less than S
