 * A PartialJavaProjectModel is useful if you want to query only very specific parts of code.
 * More specifically, a PartialJavaProjectModel is like a view/filter on an existing JavaProjectModel:
 * You can set it up such that you're querying only certain AST subtrees. 
 * (, whereas in a normal JavaProjectModel, you can only filter at the level of entire compilation units..)
