/**
 * 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.
  • *
