// This class is a simple helper for parsing INI-style assignments, in the typical form of:
//    variable = value
//    filename = SomeString.txt
//    integer  = 15
//
// This parser supports both '//' and ';' at the head of a line as indicators of a commented
// line, and such a line will return empty strings for l- and r-value.
//
// No type handling is performed -- the user must manually parse strings into integers, etc.
// For advanced "fully functional" ini file parsing, consider using wxFileConfig instead.
