 /**
+ * Exactly the same as LightCodeInsightFixtureTestCase except uses TempDirTestFixtureImpl instead of LightTempDirTestFixtureImpl.
+ * This is because the light temp dir stuff fails to work in some cases because it's in-memory file system protocol "temp:" is
+ * invalid in the eyes of the URL class, which causes URL exceptions.  For instance, the Json manifold creates a URL from the resource files.
+ *
+ * see https://www.programcreek.com/java-api-examples/?code=manifold-systems/manifold-ij/manifold-ij-master/src/test/java/manifold/ij/SomewhatLightCodeInsightFixtureTestCase.java
