rewrote adaptive view stuff so we can use it on all types of views
(model-based, multi timestep, multi-mesh)

- temp fix in Open to delete obsolete views

don't use model->bounds() here: it's costly!

  integer tags per step data
- ported Eigenvectors and StreamLines plugins to the new post-pro API

add a Universal Transverse Merctor field, add latitude / longitude and UTM coordinates in Plugin/GSHHS.cpp

- replaced "Mesh.ContrainedBackgroundMesh" by "Mesh.CharacteristicLengthFromPoints" and
  "Mesh.CharacteristicLengthExtendFromBoundary"

- fixed MED IO when numComp > 9

******************************
*   WARNING - PLEASE TEST    *
******************************

- changed I/O so that we NEVER change vertex number ids once a mesh has
been generated (or loaded)

- removed dataIndex from MVertex: stepData in PVewDataGModel now directly
uses the vertex/element number ids. This can lead to increased memory
use in corner cases (for which PViewDataList works fine, so it's not a
big deal), but it is simpler and faster

- deprecated "Complex Volume"

- moved some mesh creation utility routines in GModel::
- new MElementFactory
- fixed bad bg mesh index

untabify

added nodal interpolation functions & related stuff
