API GetGuildBankTabPermissions

Gets display / player's access info. Limited data available without bank proximity.
 canView, canDeposit, canEdit, stacksPerDay = GetGuildBankTabPermissions(tab)
==Arguments==
:;tab: - guild bank tab number
==Returns==
:;canView: - 1 if the selected rank can view this guild bank tab, nil otherwise.
:;canDeposit: - 1 if the selected rank can deposit to this guild bank tab, nil otherwise.
:;canEdit: - 1 if the selected rank can edit the bank tab text, nil otherwise.
:;stacksPerDay: - Amount of withdrawable stacks per day or 0 if none.
==Example==
 local canView, canDeposit, canEdit, stacksPerDay = GetGuildBankTabPermissions(1);
 if canDeposit then
 DEFAULT_CHAT_FRAME:AddMessage("Can view, deposit and retrieve " .. stacksPerDay .. " stacks a day on tab 1.");
 elseif canView then
 DEFAULT_CHAT_FRAME:AddMessage("Can view and retrieve " .. stacksPerDay .. " stacks a day on tab 1.");
 else
 DEFAULT_CHAT_FRAME:AddMessage("Can not view tab 1.");
 end
===Result===
: If you are the guild master, this will return data for the rank you currently have selected in guild control. Else, it will return data for your own rank.
: Guild masters can always view, deposit and withdraw without limits; this function does not properly return that. Use IsGuildLeader() if you want to know if this is the case.
: Note that being able to deposit implies being able to view.
