When dealing with data types where no 1:1 mapping to np.type is possible, the code needs to have more possibilites to modify column properties. In particular, this commit addresses - DateTime columns (exported as ISO 8601 string, column index put into parse_csv's parse_dates argument) - Integer & Long Integer columns which may be NULL and promotion rules into np.float_ (either all int columns or the ones not markes "NOT NULL") - There were no tests at all. This commit introduces a few basic tests for column parsing.
