/**
* A base class that #BOARD loading and saving plugins should derive from.
*
* Implementations can provide either Load() or Save() functions, or both. PCB_IOs throw
* exceptions, so it is best that you wrap your calls to these functions in a try catch block.
* Plugins throw exceptions because it is illegal for them to have any user interface calls in
* them whatsoever, i.e. no windowing or screen printing at all.
*
*The compiler writes the "zero argument" constructor for a PCB_IO automatically if you do
* not provide one. If you decide you need to provide a zero argument constructor of your
* own design, that is allowed. It must be public, and it is what the #PCB_IO_MGR uses. Parameters
* may be passed into a PCB_IO via the #PROPERTIES variable for any of the public API functions
* which take one.
*
*
* <pre>
* try
* {
* PCB_IO_MGR::Load(...);
* or
* PCB_IO_MGR::Save(...);
* }
* catch( const IO_ERROR& ioe )
* {
* // grab text from ioe, show in error window.
