Refactor List in PointerDB (#163)

Browse Source 
* Refactor List in Pointer DB

* Fix pointerdb-client example

* Fix issue in Path type related to empty paths

* Test for the PointerDB service with some fixes

* Fixed debug message in example: trancated --> more

* GoDoc comments for unexported methods

* TODO comment to check if Put is overwriting

* Log warning if protobuf timestamp cannot be converted

* TODO comment to make ListPageLimit configurable

* Rename 'segment' package to 'segments' to reflect folder name
