/**
* Open a project or set of files given by @a aFileList.
*
* This is generalized in the direction of worst case. In a typical case @a aFileList
* will only hold a single file, like "myboard.kicad_pcb" because any #KIWAY_PLAYER
* is only in one #KIWAY and the #KIWAY owns the #PROJECT. Therefore opening files
* from multiple projects into the same #KIWAY_PLAYER is precluded.
*
* Each derived class should handle this in a way specific to its needs. No filename
* prompting is done inside here for any file or project. There should be no need to
* call this with \a aFileList which is empty. However, calling it with a single
* filename which does not exist should indicate to the implementer that a new session
* is being started and that the given name is the desired name for the data file at
* time of save.
*
* This function does not support "appending". Use a different function for that. Any
* prior project data tree should be cleared before loading the new stuff. Therefore,
* one of the first things an implementation should do is test for existence of the first
* file in the list, and if it does not exist, treat it as a new session, possibly with
* a UI notification to that effect.
*
* After loading the window should update its Title as part of this operation. If the
* #KIWAY_PLAYER needs to, it can load the *.pro file as part of this operation.
*
* If the KIWAY_PLAYER cannot load any of the file(s) in the list, then it should say
* why through some GUI interface, and return false.
*
* @param aFileList includes files that this frame should open according to the knowledge
* in the derived wxFrame. In almost every case, the list will have only
* a single file in it.
* @param aCtl is a set of bit flags ORed together from the set of KICTL_* \#defined above.
* @return true if all requested files were opened OK, else false.
