sql_well::exec_sql_and_return_rowid method added
WPI: fix some border edges was absent
WPI: add iterator over virtual cell vertices array with ondemand calculation of vertices coords
WPI: make strategies and PODs independent of source arrays types
fix win compile
WPI: add implementation of trimesh with support of different cell vertex iterators (with carray_traits backend)
WPI: minimal corrections according to new trimesh implementation
WPI: minimal changes to fractures and compdat calculation according to new trimesh
WPI: modify VTK mesh borders drawing algorithm according to new trimesh + output only unique points
WPI: add on-the-fly cell coords calculation using tops_iterator as WPI stratefy traits
WPI: add GRDECL mesh creation and initialization function to handy_mesh interface
WPI: add trimesh::impl specialization for online_tops_traits
WPI: fix tops_iterator and make it work through raw pointer to rs_smaesh_iface
WPI: misc compile fix to helpers structure
WPI: switch to online_tops_traits by default for 2D and 3D WPI strategies
WPI: alternative implementation of tops_iterator with buffer filling on dereference operation
WPI: implement two strategies for tops_iterator

First strategy implies that iterator directly contsins buffer for
storing cell vertecies coords, as earlier.
Second strategy (bufpool_ti_traits) manages a pool of unique buffers, so
that many iterators with same cell_id will share a pointer to single
buffer. That strategy helps even more reduce memory consumption
primarily for VTK mesh drawing.
WPI: add new WPI strategy traits corresponding to bufpool tops_iterator strategy
WPI: add trimesh implementation for bufpool tops_iterator strategy
WPI: use bufpool tops_iterator strategy for VTK-related algorithms
