Resolve #29 - Fix the unit test for ExceptionExtensions to detect Mono

When running against the official .NET framework, this test does not behave as
expected and thus should be ignored.  This commit introduces this.
Resolve #13 - Add functionality to write tabular data from 2D string arrays

Currently, this functionality transforms the 2D array into a TabularDataList
and then uses existing functionality to write the data.  This might be changed
at a later point, since it will not perform particularly well with large arrays.

* Add functionality to create a TabularDataList from a 2D array.

* Add overloads to the ITabularDataParser interface for writing data based on 2D
  arrays.

* Unit tests to match.
