[Enhancement] : In-built function's validation utility

[pacifiquem]

We repeat our selves too much while we're verifying if the number of parameters and number of arguments for native functions are the same as expected. We need to built a simple validation utility to help us avoid that. it has to be scalable so that in case we need to add further verifications it can be done easily :+1:

[pacifiquem]

That validation utility class will be in /src/lib/validator.ts

It'll have a method which is reponsible for checking if number of parameters a native function has is equal to the number of argumets it received, otherwise it'll throw an error.
