Currently, the LoadProfileReader directly set modifies certain internal members of the load components in its assign() method:

load->mProfile = read(std::experimental::filesystem::path(mPath + file->second + ".csv"), start_time, time_step, end_time);
load->use_profile = true;

I think this approach is not really nice as it requires modification in each component and also adaptations for each solver?

Shouldn't we use an analogous component to the DataLogger class: DataReader which can read CSV files and set arbitrary attributes in the simulation?

Example

DataReader reader("mycsv_file.csv");

reader.setDownSampllingFactor(2);

DP::Ph1::PQLoad load("l_1");

load.setAttributeRef("p_active", reader.column("l_1"));

reader.column("l_1") hereby returns an CPS::Attribute::Ptr which gets updated continuously.

Feedback is Welcome :)
