1. moved scan/symbol.go to new package sym and adapted all files that reference Symbol type and its values. 2. new type interval defined by begin, end and step values. 3. replaced operator-range.go with operator-interval.go. 4. replaced range operator begin:end with begin..end..step. 5. new implementation of sub-collection extraction based on new interval literal.
