Fake CPE

[VinInn]

In this PR I introduce a CPE that just returns position and error previously stored in a "map".
Typical values would be those of the SimHit.
An example of a filler from SimHits is also provided.

The main technical limitation is that it does not support multi-threading.
Given that its main use is to check tracking mostly with particle gun this is not a big issue.
