Enhanced Support for Flat File Imports

There are numerous improvements to support for importing flat files, including a simplified Flat File Sample Wizard, support for multi-character and hexadecimal format delimiters and enclosures, simplified support for fixed format fields, and support for bulk flat file loads into heterogeneous targets.

Flat files are frequently used for simple and high-performance data movement in ETL applications. These changes improve ETL developer productivity and provide more flexible handling of more types of flat files in more scenarios.
