+Parameters:    toCheck - VAT number be checked.
+
+This function checks the value of the parameter for a valid European VAT number.
+
+If the number is found to be invalid format, the function returns a value of false. Otherwise it
+returns the VAT number re-formatted.
+
+Example call:
+
+  if (checkVATNumber (myVATNumber))
+      alert ("VAT number has a valid format")
+  else
+      alert ("VAT number has invalid format");
