How to make a LiveSplit component:
-start a new C# project. Select "class library" (dll) as the type of project | Important: Make sure to use a .net framework 4.6.1 class library
-add references to LiveSplit.Core.dll and UpdateManager.dll to your project (you are going to need to use the LiveSplit.UI.Components namespace throughout the project)
-add a new class to your project that implements the IComponent interface or extends one of its implementing classes
-add a new class to your project that implements IComponentFactory
-make sure to implement the Create() method of this interface such that it returns an instance of the component class that you made
-add a ComponentFactory attribute to your AssemblyInfo.cs file and give it the type of your factory class like so
[assembly: ComponentFactory(typeof(MyComponentFactory))]
