/*	class TapData
	-------------

	Subclass of "TapeData".

	A "TapData" instance contains data from a .tap file or converted to .tap file format.
	A "TapData" instance contains one data block.

	As all TapeData classes TapData defines or implements conversion creators for CswBuffer:
	- new TapData(CswBuffer const&) and
	- new CswBuffer(TapData const&, uint32 ccps).

	And static file i/o methods:
	readFile (cstr fpath, TapeFile&) and writeFile (cstr fpath, TapeFile&)
