This is the largest index, not the size of the domain of indices. For example, create the largest vector via `Vector(int, INDEX_MAX + 1)`. Also, note that the spec does not specify a value for `GrB_INDEX_MAX`, only that the implementation define it, so it may be backend-dependent.

INDEX_MAXmay be a nice global value to expose. The GraphBLAS spec doesn't have many of these globals.This is the largest index value, not the size of the domain of indices. For example, create the largest vector via
Vector(int, INDEX_MAX + 1). Also, note that the spec does not specify a value forGrB_INDEX_MAX, only that implementations define it, so it may be backend-dependent.Alternatively, we could instead define
MAX_SIZE, which would beGrB_INDEX_MAX + 1. I think this is much more natural to use; e.g.,Matrix(int, MAX_SIZE, MAX_SIZE). I don't think we need bothINDEX_MAXandMAX_SIZE.So, which to y'all prefer,
INDEX_MAXorMAX_SIZE? Feel free to suggest different names too.CC @michelp @jim22k @SultanOrazbayev
