Enhancement: It is now possible to duplicate a certain meteo parameter when reading data with MeteoIO. This feature is especially useful when one parameter needs to be filtered in two different ways (e.g. a running average spanning 5 hours and one spanning 48 hours). The syntax to use in your io.ini:

[Input]
COPY::TA2 = TA

This means that a new meteo parameter called TA2 will be added when reading meteo data from an IO source and that this new parameter will be initialized with the value of MeteoData::TA. Thus there is a copy of TA called TA2. This copy can be now used to set up a specific filter:

[Filters]
TA2::filter1 = mean_avg
TA2::arg1 = right 5 3600
