284. Adding "KeyHoleShape" cpmmand into AFC Engine

[FedorSherstyukBroadcom]

• AfcManager.h:
  • Related functions and data members added into AfcManaged class definition:
    • importKeyHoleShapeParameters() reads optional input keyhole shape parameters file
    • runKeyHoleShapeAnalysis() computes heyhole shape
    • generateKeyHoleShapeJson() generates JSON document with keyhole shape
    • _keyHoleShape - keyhole shape (maps semicircle angles to distances)
    • _keyHoleAobStepDeg, _keyHoleMinFreqMhz, _keyHoleMaxFreqMhz, _keyHoleFreqStepMhz, _keyHoleRadiusKm, _keyHoleRxAntennaRegex -- Parameters from keyhole paremeters input file or default values
• AfcManager.cpp
  • setCmdLineParams() "KeyHoleShape" added to help message for --request-type parameter
  • initializeDatabases() rearranged to accommodate KeyHoleShape request: it ignores state boundaries, but uses UNII5 to UNII8 frequency range. Section for "KeyHoleShape" request added - it reads FS database
  • importGUIjson() Section for "KeyHoleShape" request added. It has parameter file, but it is optional, so if file is absent this function does not throw foe "KeyHoleShape" request - it calls importKeyHoleShapeParameters()
  • exportGUIjson() Section for "KeyHoleShape" request added - it calls generateKeyHoleShapeJson()
  • compute() Section for "KeyHoleShape" request added - it calls runKeyHoleShapeAnalysis()
  • importKeyHoleShapeParameters() added. It documents JSON file structure and applkying defaults to parameters
  • runKeyHoleShapeAnalysis() added. It computes keyhole shape
  • generateKeyHoleShapeJson() added. It generates keyhole JSON
