Add MethodSource.clear_cache
We often need to clear cache. For example, in web application development, when we changed source code, we would like the change applied to the app server without reboot. In the case of a Rails application, this requires the following configuration: ```ruby Rails.application.configure do config.to_prepare do MethodSource.instance_variable_set(:@lines_for_file, {}) end end ``` It seems so ugly, isn't it? So I feel we need to add `MethodSource.clear_cache` interface. ```diff Rails.application.configure do config.to_prepare do - MethodSource.instance_variable_set(:@lines_for_file, {}) + MethodSource.clear_cache end end ```
