Event System Design

[kpraveenkumar]

Template class to explicitly construct a function object and execute the function object with arguments using parameter pack. C++17 has invoke feature which executes any callable with any number of arguments using parameter pack.

EventSystem has interfaces which allows to register functions and Execute the function based on event id which is generated during registration or Execute all functions based on Event type.

I tried std::vector<std::function<void, void (*)(void *)>> as common storage/generic callable container for all callable and give a generic event id for all events to invoke again but faced issue in reinterpret_cast of callable.

enum class is used to ensure type safety
