Fix with scaling of bounding box in ProjectCAD and add a Star CCM regression test

There was an incorrect scaling of the bounding box of the CAD surfaces in ProjectCAD which gives the bounding box in mm rather than meters. Modification was made to the bounding box scaling to fix the issue.

Also added a regression test from a ccm file which is how the original issue was identified and made libccm 2.6.1available through the distribution provided by Visit
