/**
* Converts given object to Class
array.
* Conversion rules:
*
* null
value is returned as null
* - object of destination type is simply casted
* - single Class is wrapped in 1-length array
* - string value is converted to string array (from CSV format) and
* then each element is converted
*
*
* This converter supports custom syntax for defining array of classes in a String:
*
* - The following chars are delimiters: {@code ,;\n}.
* - Blank lines are ignored
* - Lines that starts with '#' (after trim) are ignored.
*
