Clarify "Visibility must be declared" in the context of aviz

[jrfnl]

Related to #98 and #99

From the currently published PSR-PER (and not changed in master):

4.3 Properties and Constants¶
Visibility MUST be declared on all properties.

For the purpose of automated tooling and keeping aviz in mind, should the above be interpreted to mean "the get/read visibility must always be explicitly declared, independently of a potentially declared write visibility" ? Or should it be interpreted to mean "as long as there is any visibility declared, be it aviz or non-aviz, this rule is satisfied" ?

Edit: just for the record - I presume the latter is the case based on #99, but just want to make sure

Good catch. I agree, it should be understood as "at least some kind of visibility is specified." Implicit public-read when specifying public(set) is a nice feature, and we don't want to forbid it. 😄 I'll see if I can clarify the language.

Thanks for confirming @Crell . I'll proceed for PHPCS based on this statement.
