             Summary: Add Span classes to handle checks for overlaps, containment, equality, etc.
                 Key: LANG-1387
                 URL: https://issues.apache.org/jira/browse/LANG-1387
             Project: Commons Lang
          Issue Type: Improvement
          Components: lang.*, lang.math.*
    Affects Versions: 3.7
            Reporter: Claude Warren


This is a contribution of a span class as discussed on the mailing list.

The classes are int and long based and can:
 # determine if points are within the span.
 # determine if one span contains another span
 # determine if two spans overlap
 # do not have to have 0 (zero) as the index origin.
 # determine the length of the span
 # determine the last position in the span.
 # determine the first position in the span.

Changes to Number Utils required to detect underflow and overflow calculations.
