883196981d ENH: add offset support to stringOps::split functions
- for example,

     string buffer = ...;
     SubStrings<string> split;
     {
         auto colon = buffer.find(':');

         if (colon != std::string::npos)
         {
             split = stringOps::splitSpace(buffer, colon+1);
         }
     }

    Not really possible with a substr() since that would create a new
    temporary which then disappears.  Similarly awkward to split and
    then scan for the ':' to decide how many to discard.

ENH: add pop_front() and pop_back() methods to SubStrings

- the content is trivial enough (a pair of iterators) and the total
  number of elements is usually reasonable short so that removal of
  elements is inexpensive

  For example,

     string buffer = ...;
     auto split = stringOps::splitSpace(buffer);

     if (!split.empty() && split[0].str() == "face")
     {
         split.pop_front();
     }

4f43f0302d ENH: additional Map/HashTable constructors and ListOp functions
- construct Map/HashTable from key/value lists.

- invertToMap() : like invert() but returns a Map<label>,
  which is useful for sparse numbering

- inplaceRenumber() : taking a Map<label> for the mapper

ENH: construct/reset CStringList for list of C-strings
