Code Inspection: Data function

This inspection warns if data property of Vue component is not a function.

When defining a component, data must be declared as a function that returns the initial data object, because there will be many instances created using the same definition. If we still use a plain object for data, that same object will be shared by reference across all instances created! By providing a data function, every time a new instance is created, we can simply call it to return a fresh copy of the initial data.
