Document ITypeFinder

[hikalkan]

ITypeFinder can be used to discover types in the application, even before the dependency injection registration phase completed.

Example usage:

public override void PreConfigureServices(ServiceConfigurationContext context)
{
    var typeFinder = context.Services.GetSingletonInstance<ITypeFinder>();
    foreach (var type in typeFinder.Types)
    {
        if (type.IsAssignableTo<Control>())
        {
            // do something...
        }
    }
}

After the dependency injection phase completed, you can inject ITypeFinder into any class.

ITypeFinder makes it easy to find all types of the application without manually searching all the assemblies. It also makes the assembly search only once, so it is optimized.

There is also IAssemblyFinder to get all assemblies in the application.

Note that assemblies and types are returned only for the assemblies with AbpModule classes.

I added an extension method, so we can get it using context.Services.GetTypeFinder() method.
