/*
The following code provides configuration for dynamically instantiating classes.

The first class, `Foo`, shows how to create a basic class. It has a single property
where `property_type` refers to the data type of the value. This might be a primitive
or it may be a reference to another class. The value may be a single value (as 
with `Baz->twitter_handle`), or it may be an array (as with `Bar->number_names`).

`Bar` has two properties, a `StringCollection` with the variable name `number_names` and the
array of values following that. And it depends on a reference to an instance of `Baz` which is
instantied within the `Bar` configuration. 

`Baz` maintains a single property which is a string identified by `twitter_handle` having the 
value of `@tommcfarlin`.

There are other considerations not shown here (such as visibility modifiers, etc.). But the idea
of instantiating classes at runtime with dynamic data can be done using a configuration file so
we aren't constantly hopping through classes to change values (which is helpful during development
time).
