/*!
Add a dynamic property of the type @a type and with the name @a name.
@a Group gives the grouping name which appears in the property editor and
@a doc shows the tooltip there.
With @a attr, @a ro and @a hidden the behaviour of the property can be controlled.
@a attr is an OR'ed value of Prop_ReadOnly, Prop_Transient, Prop_Hidden or Prop_Output.
If no special attribute should be set Prop_None can be set (or leave the default of 0).
For convenience the attributes for 'Read-Only' and 'Hidden' can also be controlled with
the values @a ro or @a hidden. This means,
@code
addDynamicProperty(..., ..., "Base","blah", Prop_ReadOnly | Prop_Hidden);
@endcode
is equivalent to
@code
addDynamicProperty(..., ..., "Base","blah", Prop_None, true, true);
