Port ElevationModel class from JTS

Closes #1070

Differences from JTS:

  • Cells are all initialized upfront, no heap allocations
  • CoordinateSequence::hasZ implemented as non-virtual
  • ElevationModel::populateZ uses CoordinateFilter instead of CoordinateSequenceFilter (see note 1)

Note1:

Using CoordinateFilter instead of CoordinateSequenceFilter
allows CoordinateSequence to clear the dimension cache which
would otherwise not properly set the sequence as having Z
(see #435)

Note: See TracTickets for help on using tickets.
