// The crafting recipes M2DA contains 78 rows with ID from 0 to 91. There are gaps in the sequence
// and we cannot predict where they appear. Looping over every row to find out would be inefficient, 
// however we can use the GetM2DARows function to tell us how many actual rows there are and then
// use GetM2DARowIdFromRowIndex to convert the row number into the entry's ID number.
