2 * Importer controller
3 *
4 * The importer controller handles the uploading of tabular, comma delimited and Excel format
5 * based files. When uploaded a preview is shown of the data and the user can adjust the column
6 * type. Data in cells which don't correspond to the specified column type will be represented as "#error".
7 *
8 * The importer controller catches the actions and consecutively performs the
9 * logic behind it.
