Pdf Export - enhance output (#167)
Browse files Browse the repository at this point in the history 
* make functions private ; remove redundant initializers

* remove Chartinfo coding - it was always null

* make pdfheight class variable again - used in other functions too

* remove non-used  variables/assignments

* Copyright / Imports

* make global myparser --> OSParser instead of AllParser to use getHostName etc .. there is no other ParserType than OSParser

* PDF document properties

* IndexPage will show Hostname, OsType, Date, Timeline,

* On Each Page
- reposition page number to avoid overlap in footer
- show hostname and date in header

* checkStype import
