Document the case where an interface has two Create methods with same number of arguments

[salfab]

for classes with two constructors and factories with two Create methods: make sure the names of the arguments are different in both constructors.

the trick is to name the arguments differently if they don't already have a different signature.

as long as the names of the method match the names of the constructor, it should work and select the correct constructor.
