Hi [~andralungu],

you are right, we need a way to pass the types. Also, field / line delimiters and other options like ignore comments etc. that are already provided by CsvReader would be nice.
Instead of passing all of these as arguments, maybe we could do something similar to what CsvReader does and have e.g. an EdgeCsvReader class with fieldDelimiter(), lineDelimiter() etc. and a types() method which will return a Graph. What do you think?
