readability: changed variable names and some other stuff
readability: changed tempSlot to currentSlot, cleaner.
readability: fixed indentation. functionality: x=y-1 instead of x=y; y--;

[readability]
	Geany screwed the indentation.

[functionality]
	"nUsable = nNodes - 1;" instead of "nUsable = nNodes; nUsable--;", letting the compiler handle it.
functionality: changed from using uint64_t to unsigned int

llist.hpp:
	Didn't compile with uint64_t, also thought it might be slow.
