It's in the comments in HexPosition.cs. You use add and getkey. For example, if you have a cell called cell and you want to assign blue to a variable called "color", you'd use cell.add("color", Color.blue); and to read it you'd use cell.getValue("color"); which would return Color.blue.

This functionality is used in the Unit class, which sets the unit that's in a given cell to the variable "Unit".

You can also use clear(String key) to clear a variable, constainsKey(String key) to check if one exists, and flag(String key) to create one with a value null, which is nice if you only care if it exists rather than needing an actual value. This is used for the key "Obstacle", since I only care if one exists and I don't care about the type. A more advanced version of this might have different obstacles that certain units can cross, in which case Obstacle will be changed to be used as a variable instead of a flag.

The flag command is used in HexGrid.cs, and the containsKey command is used to check for one in AStar.cs. Also, the containsKey command is used to check the presence of a unit in AStar.cs.
