changed forward class decl with include
Removed out of date comments ->

There was a 200 line comment at the bottom of the file talking about the .HIST## format, but it didn't match the info in the UTChem 9.x user guide, so I deleted it.

partially refactored ::parseAsWellHistoryData

Still needs work, would like to get rid of sscanf use.

uncommented line ->

I had a section of code commented out, with a comment that IDW was used as an identifier in completely different contexts within INPUT. According to the UTChem 9.x User Guide, it should be only re-used on a per well basis.

I'm wondering if that message dates back to before we realized there was a difference between UTChem 9.3 and UTChem 2011_7, etc.
change var names to match UTChem User Guide.
Removed obsolete "deviated" well reading

There was a check for idir == 4, but according to the 9.3 user guide, idir can only be 1, 2, or 3. This was for 'deviated' wells, but 'deviated' doesn't appear in the 9.3 user guide.
Removed additional obsolete 'deviated' well code.
formatting
fixed well reading that depended on hard coded whitespace.
Formatting and comments
Started refactoring of ::buildWell ->

Switched to idiomatic chained method calls. They were grabbing pointer directly, which I found confusing and non-VTKish.
::buildWell refactoring ->

Moved vtkCellArray vtkPolyLine inside check for more than 1 pt, i.e., IFIRST != ILAST
Renamed lines to connectivity

Since it won't always be lines, but also vtkVertex.
Switched to vtkSmartPointer inside ::buildWell
Finished UTChemWellReader::buildWell refactoring

It will now draw single block wells as vtkVertex. Previously, it had been sending them over as vtkPolyLines, which wouldn't draw with only one vertex.
Removed spurious <array> include
Removed unused getCellCenter method

There were both a getCellCenter and a getCellCenters methods. getCellCenter wasn't called anywhere, so removed it. By inspection, it also looked to only be valid for orthonormal cells, too.
Changed some int vars that should have been floats to float
