Create array design from a bgx-file

[Nicklas Nordborg]

A bgx file contains array design information for Illumina arrays. The file is a gzip-compressed text file. The file also contains reporter annotations. The information we have so far is:

• The Probe_Id column should be used as the reporter id.
• The Array_Address_Id column is the Feature ID. This is the ID that is present in the raw data files. Thus, the array designs must use the FEATURE_ID as the feature identification method.
• Some of the other columns can be used as reporter annotations. We have no specification of this yet.

NOTE! The bgx file has two sections: [Probes] and [Controls]. Data from both sections should be imported.
