* \brief The ConversionUtils class converts an string expression to a QVariant Type.
* The modelmapper is build from a configurationfile and fieldtypes are given in strings
* By mapping those string expressions to the corresponding QVariant Type, we ensure the
* data is handled correctly.
*
* The number of types is *everything* mentioned in to Qt-documentation although
* it is doubtful we'll ever use everything.
*
* Instead of using the nameToType method of QVariant, we did our own translation table,
* making it possible to use Database types or any type whatsoever.
