- Added desired and coerced values and accessors to property
- Added support to register desired subscribers
- set APIs don't reallocate storage for a property value
- Renamed callback method registration APIs
- Registering 2 coercers or publishers for a property will throw
- Registering a coercer and a publisher for the same property will throw
This is useful when constructing property tree paths.
With this path, the following code would be valid:
size_t mb_index = 0;
fs_path mb_root = "/mboards";
mb_root = mb_root / mb_index;
This is a shortcut for the (in UHD very common)
mb_root = mb_root / boost::lexical_cast<std::string(mb_index);
