Enhance Curve objects to allow for non-monotone increasing ordinate

[aowen87]

Curve objects in VisIt are represented as a 1D rectilinear mesh. This is so we can support operators on Curves. However, LLNL/Engineering/GrizIt users will need to be able to construct curve objects that are a sequence of points joined by lines (think of a 2D circle for example). One way to handle such curves in current VisIt infrastructure is to use 2, 1D rectilinear mesh objects, one for the X and one for the Y both as a function of a parametric variable, u, which ranges from 0...npts-1. I believe all of VisIt's operators could be posed upon such a new style of curve object and might even offer some interesting flexibility not previously possible on operating upon curves. We should explore this.
