svSolver git hub page suggestions

[amscosta]

Hello,
As I spent a couple of hours figuring it out, just sharing some suggestion of update for the svSolver git hub page

The VTK 8.2.0 installation procedure depicted in the HPC section is appliable for single computer also.

And the following corrections as in the following picture:

vtk/install/

@amscosta Thanks for the suggestions.

I think that vtk-install is clear, just a symbol for the local VTK installation, which could really have any name.

Using cmake -DSV_USE_LOCAL_VTK=ON -DSV_VTK_LOCAL_PATH=$HOME/vtk-install/ ../svSolver would be more consistent.
