Added getQualifier and qualifier.

getQualifier returns the qualifier for the specified object in an
qualifier object. If no qualifier is available for the specified object
qualifier.status is -1 and the qualifier data is zeros.
Replaced reshapes by correct ordering of arrays.

For multidimensional data the arrays are now directly allocated using
FORTRAN ordering (order='F'). No further reshaping is necessary. This
was done for getQualifier, getAreaBase, getSignalGroup and
getSignalGroupCalibrated. The functions were tested using IDA and CEC.
