reading csv file in mathematica

When Mathematica reads a flatfile, it evaluates each field as a mathematica expression. I sometimes just want to read the entire file in as strings then perform some specific type conversion on columns. Here's a short way to import data is string fields.

The idea is to provide a shell of the algorithm and then extensive customization through functions. This is a very functional approach to creating functions. However, the package is still composed of a giant function though versus a more clever, parsing state machine.

You have options to customize line splitting, field/attribute processing, field level transformations as well a collection mechanism that allows you to collect specific input record for later use. For example, you can save the header line. The returned value is not just a data matrix, but an association with various import statistics and other collected information.

You can find the package here in a gist.
