[Rock-dev] log file converter

[Alexander Duda]

The first version of the log file converter is ready. I wrote some unit
tests but I would recommend if you are using it DON'T delete your source
files ;-).

To convert all /base/Time fields into the new version the syntax would
be:
Converter.register_converter "my_converter",Time.now,Orocos.registry do 
  register "/base/Time" do |dest,src|
    dest.microseconds = src.seconds * 1000000 + src.microseconds
  end
end

#Changing a type name:
Converter.register_converter "my_converter",Time.now,Orocos.registry do 
  register "/base/Time","/base/Time2" do |dest,src|
    dest.microseconds = src.seconds * 1000000 + src.microseconds
  end
end

#Changing an enum value
Converter.register_converter "my_converter",Time.now,Orocos.registry do 
  register "/base/MyEnum" do |dest,src|
    src = :bla if dest == :Test
    src = :bla2 if dest == :Test2
  end
end

#Converting more than one type on the same time
Converter.register_converter "my_converter",Time.now,Orocos.registry do 
  register "/base/MyEnum" do |dest,src|
    src = :bla if dest == :Test
    src = :bla2 if dest == :Test2
  end
  register "/base/MyEnum2" do |dest,src|
    src = :bla if dest == :Test
    src = :bla2 if dest == :Test2
  end
end

#Converting one field of a complex type
Converter.register_converter "my_converter",Time.now,Orocos.registry do 
  register "/base/samples/frame/Frame" do |dest,src|
	dest.time = Time.now
	exclude = [:self,"time"] 
	deep_cast(dest,src, exclude)   # auto copy+registered converters
  end
end

thoughts?
