This update removes the usage of namespaces in an effort to just be able to use A-Frame directly from an import.
These types are based on [this branch](576e4557b1/%40types) of work in my [a-frame experiements](https://github.com/devpaul/aframe-experiments) repo. Please take a look over there to see more complete usage and examples.
* Add new PropertyTypes
* A-Frame: Expand registerComponent test.
* Add generics to properties, components, and systems.
* Add missing ShaderDefinition interface.
* Add missing event data.
* Add missing throttle and throttleTick functions.
* Update Typescript version
* Use classes for component, system, and geometry
* Add tests for class inheritance.
* Improve defaults, rename ComponentBase -> ComponentDefault
* Saw the sign - many simplifications, return to interfaces
Can't extend a class definition that doesn't exist at runtime, so we need to use interfaces?
* Remove unnecessary generics
* Simplified some references, added a couple tests.
* Moving undefined system from generic to property.
* Revert "Update Typescript version"
This reverts commit 43ef72cef75b0bcee2d04eddcaa0f594290ec46f.
