Changes

<li>map import data to fields, groups, tags. Also do a large amount of data wrangling (normalization; and ETL) to get source data in a format suitable for use with CiviCRM. The data that I have is "composite" because it has individuals embedded inside organization records. So I needed to extract and flatten out contact records from their organization records; plus create and maintain a simple "external ID" system to relate them after import. This means parsing, slicing and dicing, string manipulation and making corrections or formatting data a particular way. I almost installed Pentaho Data Integration (kettle) because that tool is (supposedly) built for this job. <ref>But like since version 3, Pentaho still doesn't work even at 5. The install docs are missing. The thing failed to even load, with no error.</ref>
