/**
* Function OpenProjectFiles
* is abstract, and opens 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.
* <p>
* 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 aFileList which is empty. However, calling it with
* a single filename which does not exist should indicate to the implementor
* that a new session is being started and that the given name is the desired
* name for the data file at time of save.
* <p>
* 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.
* <p>
* 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.
* <p>
* 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.
* <p>
* 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 bool - true if all requested files were opened OK, else false.
