- also made some change to get a more functionnal detector

        - Detector now read there configration through NPIntputParser
        - File is read once and then the parser is passed on
        - Allow for smaller ReadConfiguration method
        - NPS and NPL ReadConfiguration almost identical
        - Support for unit
        - Draw back: strongly rely on file indentation

* calibration
        - Avoid memory leak
        - Prevent root from deleting it twice

Struct for mapping silicon scorer output

Fixes #18

* Fixing nptool.csh

        - csh is so poor even alias cannot be defined
        - pretty much useless

        - Less libraries are loaded
        - nicer flag to load the libraries
        - comply with the rpath method of linking

        - nps compilation was done before npl compilation
