/**
 * @assertion void fillRange(int start, int end, [E fill])
 * Sets the objects in the range start inclusive to end exclusive to the given
 * fillValue.
 * The provide range, given by start and end, must be valid. A range from start
 * to end is valid if 0 <= start <= end <= len, where len is this list's length.
 * The range starts at start and has length end - start. An empty range (with
 * end == start) is valid.
 * @description Checks that the given range is filled with [fill] value.
