The utility class FilePath wraps an instance of boost::filesystem::path. Using FilePath allows for easy comparision of
file paths on different platforms using absolute or relative paths. Whereever file paths are compared, this wrapper
should be used.
This change parses the TokenLocations of scopes of classes, structs, functions, methods, namespaces and enums and
saves them in Storage with type LOCATION_SCOPE. The TokenLocations of these nodes are just their name declarations now.
Scope locations are displayed in blue color in the code view.
This change adds structures for saving TokenLocations in the Storage and improves the location derival in the
ASTVisitor:
* TokenLocation saves an Id of a Token. For each Token two TokenLocations are created for both start- and endpoint. They
keep a reference to each other and know whether they are start or end.
* TokenLocationLine saves all TokenLocations in a line and the lineNumber.
* TokenLocationFile saves all TokenLocationLines of a specific file and the filePath.
* TokenLocationCollection saves multiple TokenLocationFiles.
* TokenLocation can derive it's lineNumber and filePath through references to first TokenLocationLine and from there to
TokenLocationFile.
