- Adopted deferred WGI_VALUE design for Result type of *_parameter and similar functions

Browse Source 
- Adopted the ITERATION_CURSOR [WGI_VALUE] design for *_parameters and similar functions
- renamed parameter as item
- provided helper function to handle "string" value parameters

Experimental for now.
