[Feature Request]Reflection based atributes

To bring this great project to a new level of freedom, we can add a bunch of reflection based attribute. The basic concept is use field/property/method name as attribute param, and use reflection to retrieve the value and decide how to draw.

For example:

public class DynamicShowIfAttribute : Attribute
{
	public string showMethod;
	public string enableMethod;

	public DynamicShowIfAttribute (string showMethod, string enableMethod = null)
	{
		this.showMethod = showMethod;
	}
}

public class Foo
{
	[DynamicShowIf (nameof (showVal), nameof (EnableValFunc))]
	public int val;

	bool showVal = true;
	bool ShowVal => true;

	bool EnableValFunc ()
	{
		return true;
	}
}

A important use case is handle the class inheritance. For example, I usually put a help info box on top of my scripts. Without reflection based features, it is impossible to change that message in derived classes.

Hello,

from now, all condition drawers (EnableIf, HideIf, etc.) are able to use members of the parent class to pass values:

[DisableIf(nameof(GetFloatValue), 2.0f, Comparison = UnityComparisonMethod.GreaterEqual)]
public int var2;

public float GetFloatValue()
{
	return 1.6f;
}
