/**Class to parse attribute-assignments from a string and sets its values
 into attribute-values.

 Use this class like the following:

\verbatim    std::string file;
    ANumeric    size;
    ATimestamp  time;

    AttributeParse attrs;
    ATTRIBUTE (attrs, std::string, file, "File");
    ATTRIBUTE (attrs, ANumeric, size, "Size");
    ATTRIBUTE (attrs, ATimestamp, time, "Time");

    try {
       attrs.assignValues ("File=\"ADate.cpp\";Time=01012000 121005;Size=18180");
    }
    catch (YGP::ParseError& e) {
       // Errorhandling
    }
\endverbatim

 This example would assign the values \c ADate.cpp to \c file, \c 18180 to \c
 size and the <tt>1st of January 2000, 12:10:05</tt> to \c time.

 MEATTRIBUTE defines an attribute whose values are restricted to the
 values in the respective YGP::MetaEnum.

 \note Tthe order of the attributes while declaration and during parsing
       does not need to be the same!
