Subject: API interface to SVS objects
Name: Nick Crookston
Date: April 12, 2013
Variants affected: All

Description: Added API calls to support interaction with the SVS objects. 

Impact on users: None unless someone is using the features.

SVS keyword impact: Added a flag on field 7 that suppresses the actual
writting of the image files yet turns on the SVS calculations.

common/SVDEAD.F77  Added SNGCNWT (now) and CWDWT (at r736)
base/src/svkey     Added the ability to suppress output. 
base/src/svsnad.f  Added processing of SNGCNWT

base/src/svsnage.f Added code to process snag and cwd state
base/src/svout.f   Added code to skip write statements when JSVOUT is
                   negetive. Also fixed several type issues to clear up
                   compiler warnings.
pg/src/putstd.f    Put SNGCNWT and CWDWT
