**Before this commit**
The usePosition hook takes two arguments:
- the target element (could be a function returning an element)
- the positioning options, which are optional.
This API is a bit weird for these reasons:
- the target argument's type is variable
- the "popper" option is not very meaningful and has a
default value of "popper", which is not clearly stated
**After this commit**
The usePosition hook now takes three different arguments:
- first is "refName", which is the reference to the element to position
in the template
- then is "getTarget", a callback that must return the target element,
- finally the "options"
