/**
The Interface of the EntryPoints .entrypoint files
Every .entrypoint file it's an object that must have two required fields:
- getPreloadProps(...) function that will return the description of preloaded
queries and preloaded (nested) entry points for the current entry point
- root - JSResourceReference of the module that will render those preloaded queries
TEntryPointParams - object that contains all necessary information to execute
the preloaders (routeParams, query variables)
TPreloadedQueries - queries, defined in the root components
TPreloadedEntryPoints - nested entry points, defined in the root components
TRuntimeProps - the type of additional props that you may pass to the
component (like `onClick` handler, etc) during runtime. Values for them
defined during component runtime
TExtraProps - a bag of extra props that you may define in `entrypoint` file
and they will be passed to the EntryPointComponent as `extraProps`
