…lare' or 'export' -- more POSIX friendly
Added stanza to match variable assignments. This is specifically to be more useful to POSIX-compliant scripts where 'declare' is not a thing. All variables matched this way are set as type 'String'. Though this does likely match the same variable more than once, that does not appear to be an issue in the end product.

Hello, in writing POSIX-compliant scripts, we are unable to use the 'declare' syntax, thus I have added a stanza to match simple variable assignments. Variables matched in this way are given a type of 'String'. This allows Doxygen to catch and add these to generated documentation. Though it almost certainly results in multiple matches, in my (admittedly limited) testing, the end-result looks fine.
Though this project is 'bash-doxygen' and not 'posix-doxygen', I believe this to be of value to many bash users as well, since it is not really common practice to use the 'declare' keyword from what I have seen.
