Changed return type of meta_variable to be WGI_STRING_VALUE ... since the meta variable can not be anything else.
Made sure REQUEST_URI starts with one and only one slash
Internal implementation: the _table now compares object
Removed SELF variable ... at least for now
Be sure to provide a REQUEST_URI even if the underlying connector does not.
- 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.
