Detailed Description

Manages a multi value string such as student's answers to a multiple choice question. Although most answers are single-valued text strings, MultiChoiceField supports multi-valued answers. This class encapsulates the multiple answers into a single string, separated by comma characters, so that all answers can be managed the same way. The class uses an ad-hoc comma-separated format for packing arrays into strings while escaping internal comma signs by doubling them.
