Usage example
-------------

// Get the CSV content - you can load it from a file, but it has to be converted to a string
var csvContent = @"FirstName,LastName,Email
John,Doe,johndoe@test.com
Mary,Smith,marysmith@test.com";

// Parse the string into a List of Dynamic objects
var csvList = ParseCsv(csvContent);

// Check if it has valid CSV content
if (csvList!=null && csvList.Count>0){
    // Loop throught all lines of the CSV (skipping the header)
    foreach(var line in csvList) {
        // It's better to cast the dynamic object to strongly-typed
        string firstName = line.FirstName;
        string lastName = line.LastName;
        string email = line.Email;
    }
}

        scriptSession.SetVariable("csvContent", csvContent);
