Functions
	TEST (SatCounterDeathTest, BitCountExceeds)
	Test that an error is triggered when the number of bits exceeds the counter's capacity.
	TEST (SatCounterDeathTest, InitialValueExceeds)
	Test that an error is triggered when the initial value is higher than the maximum possible value.
	TEST (SatCounterTest, MaximumValue)
	Test if the maximum value is indeed the maximum value reachable.
	TEST (SatCounterTest, MinimumValue)
	Test if the minimum value is indeed the mimimum value reachable.
	TEST (SatCounterTest, InitialValue)
	Test initializing the counter with a value, updating it and then resetting.
	TEST (SatCounterTest, SaturationPercentile)
	Test calculating saturation percentile.
	TEST (SatCounterTest, Saturate)
	Test abrupt saturation.
	TEST (SatCounterTest, Saturate16)
	TEST (SatCounterTest, IntComparison)
	Test back and forth against an int.
	TEST (SatCounterTest, Shift)
	Test shift operators.
	TEST (SatCounterDeathTest, RightShiftNegative)
	Make sure the counters cannot be right-shifted by negative numbers, since that is undefined behaviour.
	TEST (SatCounterDeathTest, LeftShiftNegative)
	Make sure the counters cannot be left-shifted by negative numbers, since that is undefined behaviour.
	TEST (SatCounterTest, PrePostOperators)
	Test both pre and post operators.

	Test copy and move for both constructor and assignment.
	TEST (SatCounterTest, AddSubAssignment)
	Test add-assignment and subtract assignment.
	TEST (SatCounterTest, NegativeAddSubAssignment)
	Test add-assignment and subtract assignment using negative numbers.
	TEST (SatCounterTest, Size16)
	Test max and min when using SatCounter16.
	TEST (SatCounterTest, Size32)
	Test max and min when using SatCounter32.
