Validator Error Messages

[Owen Arnold]

  auto widthVectorValidator = boost::make_shared<CompositeValidator>();
  widthVectorValidator->add(boost::make_shared<ArrayBoundedValidator<int> >(0, 100));
  widthVectorValidator->add(boost::make_shared<MandatoryValidator<int > >()); // incorrect
  // widthVectorValidator->add(boost::make_shared<MandatoryValidator<std::vector<int> > >()); // correct

  declareProperty(new ArrayProperty<int>(
      "WidthVector", widthVectorValidator
      , Direction::Input), "Width vector. Either specify the width in n-pixels for each dimension, or provide a single entry (n-pixels) for all dimensions." );

now do

Algorithm alg;
alg.setChild(true);
alg.initialize();
std::vector<int> widthVector(1, 1);
alg.setProperty("WidthVector", widthVector); // Crashes out 

This last line crashes out with "Value was not of expected type." from TypedValidator, but the error was with the declaration of the MandatoryValidator. Would be better if the isValid message reflected that.
