Description
-----------

The top-level object is wxProjectDatabase, which maintains a list of wxProjectGenerator
objects. Each wxProjectGenerator object contains a list of wxGeneratorConfiguration objects,
and each of these in turn stores a list of variants which represent compiler-specific options in that
configuration. wxProjectDatabase also stores a list of generic options (again variants),
which may cause compiler-specific options to be stored in configurations.

The usage is like this. The IDE (or other calling application) adds a number of project generators
at initialization, one for each kind of compiler. For a new project, the app should call InitializeGenerators
in order to call OnInitializeDefaults for each generator, which will call back into the wxProjectDatabase
to get user-settable defaults.

The app can then set generic options. When a generic option (such as 'use debug info')
is set for a particular configuration, all generator objects are notified via OnSetGenericOption and they
translate the generic option into a specific one (for that configuration).

The wxProjectDatabase object can also be used to set compiler-specific options directly if required,
but normally this would not be required. Each wxProjectGenerator should also have the opportunity
to set initial defaults. These defaults should be editable by the user.

Each wxProjectGenerator can access the parent wxProjectDatabase object at any time, since it
may need to make a judgement about several generic settings in order to know what specific
compiler options should be set.

TODO: make a list of generic compiler options that each generator should recognise.
