+/// DECLARE_MATERIALASSET is a utility macro for MaterialAssets. It takes in the name of the class using it, the name of the field for the material, and a networking bitmask
+/// The first 2 are for setting up/filling out the fields and class member defines
+/// The bitmask is for when the material is changed, it can automatically kick a network update on the owner object to pass the changed asset to clients
