Replaces the workspace with 3 distinct registers: path, value and xreg

workspace contained a list of WalkItems, pairs of paths and values.
The new system can still hold a list of values but only one path, which is in itself a list of values.
The X register is miscellaneous. All 3 hold a list of values (which are JSON tokens)
