====== Observations ======
  * More general plotting, all parameters in data source available
  * Move parameter definitions to the setupfile
===== ObsManager->initDialog =====
 move the definitions to the setupfile
name=
sources=
plottype=synop|metar|list
options=(misc in ObsManager)
parameters.begin
dialogname= id:key:method:calc:precision:tooltip
parameters.end
 
  * dialogname - name of parameter used in dialog and command string
  * id - needed in synop/metar plot. id=TTT means that this parameter should be plotted in the TTT position
  * key - key used by the data source. bufr: descriptor,  ascii: name of column, 
  * method - how to plot the value - number, weathersymbol, cloudsymbol,  etc
  * calc - change unit, height of clouds m->code
  * precision - number of digits
===== ObsPlot::plotList =====
foreach(parameter)
  plotParam(value,method,xpos,ypos,alignment)
===== ObsPlot::plotAscii =====
To be removed, use plotList
===== ObsPlot::plotSynop/Metar =====
  * Minor changes map[id]=dialogname
===== Other changes =====
  * Criteria limits
    * today - each parameter gets reasonable value limits in initDialog
    * suggestion - use LineEdit, not slider in the dialog
===== Unsolved issues =====
  * parameters like 
    * precip last x hours
    * max wind/temp last x hours
  * Possible solution:
    * change map in ObsData to map
  * Dialog layout
