Detailed Description

A class that encapsulates name lookup information.

Users can type a wide variety of partial names when setting breakpoints by name or when looking for functions by name. The SymbolFile object is only required to implement name lookup for function basenames and for fully mangled names. This means if the user types in a partial name, we must reduce this to a name lookup that will work with all SymbolFile objects. So we might reduce a name lookup to look for a basename, and then prune out any results that don't match.

The "m_name" member variable represents the name as it was typed by the user. "m_lookup_name" will be the name we actually search for through the symbol or objects files. Lanaguage is included in case we need to filter results by language at a later date. The "m_name_type_mask" member variable tells us what kinds of names we are looking for and can help us prune out unwanted results.

Function lookups are done in Module.cpp, ModuleList.cpp and in BreakpointResolverName.cpp and they all now use this class to do lookups correctly.
