WISH: ptSrfDomChord not to have default values for uD and vD

Hi Rajaa,

Before continuing I have to see say this is a great set of tools for GH.

Back on topic --> I was just playing around with PT when I tried the ptSrfDomChord component out and had to pull the plug on my PC in order to get back to work. I have a ship's hull that has been modelled in milometers and when I plugged all the surfaces into it  there was about 15 minutes of inactivity (I went to make a cup of tea) before I tried to abort, nothing worked so after half an hour I ended up shutting down the PC with the power button as my hull is about 60,000 mm in length.

Also there is an inconsistency in the naming of ptUVCurves and ptCrvAtts. Would it be possible to make it ptUVCrvs as I type in the Create Box to generate components. (I know I can set ptUVCrv as an alias to make it easier)
