* Implement providers traversal in first precision * Implement traversal for all providers * Update traverse interface + add some tests * Refactor tests * Add tests for callable provider * Add configuration tests * Add Factory tests * Add FactoryAggrefate tests * Add .provides attribute to singleton providers * Add singleton provider tests * Add list and dict provider tests * Add resource tests * Add Container provider tests * Add Selector provider tests * Add ProvidedInstance provider tests * Add AttributeGetter provider tests * Add ItemGetter provider tests * Add MethodCaller provider tests * Refactor container interface * Update resource provider string representation * Add .initializer attribute to Resource provider * Add docs and examples * Remove not needed EOL in the tests * Make cosmetic refactoring * Ignore flake8 line width error in traverse example
