This class encapsulates information about a Scope and its dictionary of names. Since the AST::Scope is meant purely for documentation purposes, this class provides the extra information needed for operations such as name lookup (a dictionary of types, and links to using scopes).
The using directives work as follows: Using directives effectively add all contained declarations to the namespace containing the directive, but they still need to be processed separately. To handle this each ScopeInfo remembers which other namespaces it is using {using_scopes}.
One quirk is that all used namespaces are considered as a whole for overload resolution, *not* one at a time. To facilitate this 'dummy' scopeinfos are inserted into the ScopeSearch of a containing namespace, which the algorithms recognize. (TODO: consider a wrapper(?) a.la AST::Inheritance)

True only if this is a dummy Scope representing the use of another. If this is the case, then only 'dict' is set
Counts of named sub-namespaces. The names are things like "if", "while" etc. This is for the purely aesthetic purpose of being able to name anonymous namespaces like "`if `while `if2 `do" instead of "`if1 `while2 `if3 `do4" or even "`0001 `0002 `0003 `0004" as OpenC++ does.
