[Suggestion] Include small write-up about how to make use of dataref functions

[Kinyom]

Even after scouring the net for hours, I haven't been able to find a single tutorial on how to make use of/read dataref function blocks. A lot of vital values I'm looking to read seem to be locked behind these, and I can't for the life of me figure out how to use the hexadecimal bytes in the block to find the value. I've heard it relates to hardcoded functions in the game/pointers to addresses, but I haven't been able to confirm this. Some clearing up of what they mean and how to use them would be much appreciated.
