/**
Code repository - the persistent symbol store accessor.
Symbols from parsed files can be saved to the persistent symbol store.
Persistence in this case means that symbol database is never loaded into memory
and works like a usual database which executes queries.

Code repository consists from @ref Catalog objects that represent separate symbol
databases. Catalogs can be created/loaded/unloaded dynamically.
To find a symbol in the repository each catalog should be queried.

Persistent symbol store is useful to keep information about code that
never or rarely changes. System libraries are perfect examples of such code.
Symbols from code contained in project files are better stored in memory
symbol store like @ref CodeModel.
