Classes
class	AssetDatabaseHelper
	Created by Bunny83 for UnityAnswers.com - public domain, many thanks! Use the GetUniqueAssetPath function, passing in a built-in object, to get the custom path to the object. Make note of this path, and you can pass it to LoadAssetFromUniqueAssetPath to load it at a later time. Editor Only functionality.

class	EditModeIntervalEditorComponent
	This EditorOnly Class contains the function used to initializes the EditModeIntervalCallbacks, and register it with the UnityEditorApplication. This class is defined as a UnityEditor-Only-class, which allows the EditModeIntervalCallbacks class to be used, but not function, in player-only code.

class	EditorToolsOptions
	The class serializes and stores the various options for use in the UnityEditorTools module. It also contains function to display these options, in the EyEEnginesPref section of the project->settings window.

class	EditorUtil
	This class contains a variety of functions. Some are used to make accessing SerializedObjects a little easier, and others are for drawing specialized controls.

class	GameObjectExtensionEditorComponent
	Editor Adapter component for GameObjectExtensions. It allows GameObjectExtensions to potentially call certain editor function, when actually running in the editor, without the need to actually reference the editor dll Upon InitializeOnLoadMethod, this class will assign these editor functions to a delegate found in the GameObjectExtensions class. If NOT in the editor, these delegates will NOT have functions assigned to them, and so will not be invoked by GameObjectExtensions.

class	GetAssetPathPopupWindow
	Menu tool to find the UniquePath for a given asset. This is useful for finding the UniquePath for built-in objects, which can then be loaded at runtime using AssetDatabaseHelper.LoadAssetFromUniqueAssetPath

interface	IStreamable
	This interface has two functions to read and write the contents of the implementing class to the stream. They use the current position of the provided stream, which is incremented as they read/write their data.

class	LimitedListDrawer
	This class contains static function for drawing large lists. Optimized to draw only the part of the list that is being displayed, it does not slow down the system for large lists.

class	LimitedListProperty
	This is a concrete, SerializedProperty type, variant of the abstract base class, LimitedListDrawer. It defines/implements the abstract functions declared required by LimitedListDrawer, using SerializedProperties.

class	PerObjectNamedBooleans
	Allows each unique Unity.Object to store it's own key/boolean pair.

class	PropertyStats
	This class extracts and cashes various properties of a given SerializedProperty along with how large it will be drawn.

class	RenamePopupWindow
	Simple EditorWindow with a single field for entering a string.

class	ResourceSystem

class	SerializableDictionaryPropertyDrawerBase
	property drawer used to display SerializableDictionry.

class	SerializedTreePropertyDrawerBase
	SerializedPropertyDrawerBase base class used to create property drawers for any class based upon SerializableTree<T> You will need to derive your own version of this class, and specify T, in order to be able to assign it the CustomPropertyDrawer Attribute.

class	StreamableInterfaceExtension
	Contains functions that provide "constructors" for objects that implement the IStreamable interface, given a provided Stream

class	UniqueStringID
