Dealing with data using OpenCV's TrainData container in C++

Among other things, in C++, the ml module contains a class called TrainData, which provides a container to work with data in C++. Its functionality is limited to reading (preferably) numerical data from .csv files (containing comma-separated values). Hence, if the data that you want to work with comes in a neatly organized .csv file, this class will save you a lot of time.
