2005-11-03  Niv Drory  <drory@astro.as.utexas.edu>

	* ltl/fvector/fviter.h: Added postfix operator++, operator--
	to satisfy bidirectional_iterator. More <alogirithm> stuff
	usable with fvectors.

2005-11-03  Claus A. Goessl  <cag@usm.uni-muenchen.de>
	* ltl/fits.h, ltl/fitsio.h: MArray& parameters to FitsOut()
	now can be const.

2005-10-07  Niv Drory  <drory@astro.as.utexas.edu>

	* ltl/fvector.h, ltl/fvector/fviter.h: added missing 
	stl iterator traits, end iterators and end() methods,
	and operator== and operator!= for iterators. Now
	FVectors can be used with std::algorithm classes.
	* test/testfvec.cpp: added testcase for the above using
	std::copy.

2005-10-03  Niv Drory  <drory@astro.as.utexas.edu>

2005-01-28  Niv Drory  <drory@astro.as.utexas.edu>

	* option_parser.cpp: added function deleteOptions()
	* option_parser.cpp, option_parser.h: printUsage() now prints
	the options in the order they were added as opposed to 
	alphabetically. This gives more useful usage info as the options
	can be grouped logically. writeConfig() has a bool option to control
	the order of the output.

22005-01-04  Claus A. Goessl  <cag@usm.uni-muenchen.de>

	* fits.cpp, fits_header.cpp, fits_header.h:

	use the same underlying operation implementation, in fact

	implementation of all mathematical operations.
