/**
Creates a new document in a manner determined by the @a flags
parameter, which can be:
Creates a new document.
- wxDOC_NEW - Creates a fresh document.
- wxDOC_SILENT - Silently loads the given document file.
This function can either create a document corresponding to a new
file or to an already existing one depending on whether @c wxDOC_NEW is
specified in the @a flags.
If wxDOC_NEW is present, a new document will be created and returned,
possibly after asking the user for a template to use if there is more
than one document template. If wxDOC_SILENT is present, a new document
will be created and the given file loaded into it. If neither of these
flags is present, the user will be presented with a file selector for
the file to load, and the template to use will be determined by the
extension (Windows) or by popping up a template choice list (other
platforms).
By default, this function asks the user for the type of document to
open and the path to its file if it's not specified, i.e. if @a path is
empty. Specifying @c wxDOC_SILENT flag suppresses any prompts and means
that the @a path must be non-empty and there must be a registered
document template handling the extension of this file, otherwise a
warning message is logged and the function returns @NULL. Notice that
@c wxDOC_SILENT can be combined with @c wxDOC_NEW, however in this case
the @a path must still be specified, even if the file with this path
typically won't exist.
If the maximum number of documents has been reached, this function will
delete the oldest currently loaded document before creating a new one.
Finally notice that if this document manager was configured to allow
only a limited number of simultaneously opened documents using
SetMaxDocsOpen(), this function will try to close the oldest existing
document if this number was reached before creating a new document.
And if closing the old document fails (e.g. because it was vetoed by
user), this function fails as well.
@param path
Path to a file or an empty string. If the path is empty, the user
will be asked to select it (thus, this is incompatible with the use
of @c wxDOC_SILENT). The file should exist unless @a flags includes
@c wxDOC_NEW.
@param flags
By default, none. May include @c wxDOC_NEW to indicate that the new
document corresponds to a new file and not an existing one and
@c wxDOC_SILENT to suppress any dialogs asking the user about the
file path and type.
@return a new document object or @NULL on failure.
