A pair of offsets (boundary points) that can be used to denote a fragment
of an expression.
A range is said to be collapsed when start and end are equal.
When specifying a range, a negative offset can be used to indicate an
offset from the last valid offset, i.e. -1 is the last valid offset, -2
is one offset before that, etc...
A normalized range will always be such that start <= end, start >= 0,
end >= 0, start < lastOffset, end < lastOffset. All the methods return
a normalized range.
