"""
Generate a CSV file with feature vectors.

Usage: generate-test-plate-analysis.py <plate code>[.<analysis procedure>] <feature 1> <feature 2> ...

It creates a folder named <plate code>[.<analysis procedure>].csv with random data for each specified feature.
If a feature is of the form

<feature name>:<term 1>:<term 2>:...

Then a non-numerical feature with a specified list of possible values is created.

The features 'row number' and 'column number' are created automatically
