+  renamed premint.xml to prengspice.xml.
+  xml file that does preformating of verilog files.
+  add routine load_vadev to public definitions.
+  add routine load_vadev for dynamic loading of modules.
+  add dynamic loading of models. shared libs should be libNAME.so.
+  use u instance as dynamically defined models in --adms mode
