v2.1.0: version 2.1.0

Allows using an string as comment delimiter instead of just one character.

New IInidataFormatter interface allows that to define the way an IniData structure is converted to an string. The interface can be passed as an argument to an overloaded IniData.ToString(IInidataFormatter formatter) method to customize how to recreate an IniFile. This allows, for example, to read an IniFile with an specified format and persists it with a different one.
The defatult IniData.ToString() method uses a default formatter with the same settings as the configuration used to parse the file.
