 @class      NodeStyle
 @brief      Store node style information.
 @details    Store node style information. These properties affect how a node
             is displayed in TikZiT. Colors are stored in the ColorRGB struct
             to avoid any Cocoa dependency. These styles should be persistant,
             which should be implemented in a platform-specific category. For
             OS X, this is NodeStyle+Coder.
