VBA: Module, function and variable attributes

Module attributes

Module attributes are declared in the header of a module.

The following attributes are available

`VB_Createable`	defines, together with `VB_Exposed` a class's accessibility and instancing.
`VB_Exposed`	defines, together with `VB_Createable` a class's accessibility and instancing.
`VB_GlobalNameSpace`	If set to `true`, the class is associated with a default instance variable with no publicly expressible name. Compare with `VB_PredeclaredId`. The class can be accessed using the classes default instance members.
`VB_Name`	This attribute is used for both, class modules and ordinary modules: it names the module when it is imported.
`VB_PredeclaredId`	If set to `true`, the class is associated with a default instance variable whose name is equal to that of the class. Compare with `VB_GlobalNameSpace`

The default values for these attributes is false.

`VB_VarDescription`	allows to add a description to a subs and functions.
`VB_UserMemId`	specifies the DISPID for the method. If the value is 0, it specifies an object's default member function.
`VB_MemberFlags`
`VB_ProcData.vb_invoke_func`	Allows to associate a VBA function with a keyboard shortcut.

Then, there seems also to be the variable attribute VB_VarDescription

In order to be able to identify class modules when they're imported, the file's first line must(?) read

VERSION 1.0 CLASS

This line probably doesn't count as an attribute, though.
