Callback type declaration for overriding default Bidi class values with custom ones.

Usually, the function pointer will be propagated to a UBiDi object by calling the ubidi_setClassCallback() function; then the callback will be invoked by the UBA implementation any time the class of a character is to be determined.

Parameters:

	context	is a pointer to the callback private data.
	c	is the code point to get a Bidi class for.

Returns:

The directional property / Bidi class for the given code point c if the default class has been overridden, or U_BIDI_CLASS_DEFAULT if the standard Bidi class value for c is to be used.
