* New plot function for clos.etm objects

2009-6-9 Arthur Allignol <arthur.allignol@fdm.uni-freiburg.de>

* New aw argument to clos. Whether use alternative weighting
	to compute the expected change in LOS
* Implementation of the alternative weighting

* New argument to etm: delta.na which decides whether to include in
	the output the increments of the Nelson-Aalen estimator
* Implementation of the Change of Length of Stay following changeLOS 
	package. Though here, it works with left-truncated data, and 
	doesn't require competing outcomes

* New internal function ci.transfo() that transforms etm objects and computes pointwise CIs
* Modification of summary.etm that now uses ci.transform
* Modification of xyplot.etm. Uses ci.transform, and plots CI
* New data set abortion

* bug correction

2009-1-9 Arthur Allignol <arthur.allignol@fdm.uni-freiburg.de>

* Modification of sir.cont.Rd 

2008-12-9 Arthur Allignol <arthur.allignol@fdm.uni-freiburg>

* Modification of print and summary
	new arguments
* cov.dna now in C

2008-11-19 Arthur Allignol <arthur.allignol@fdm.uni-freiburg.de>

* Modification of the print an summary methods
* Now result of summary is printed via print.summary.etm()
* In etm: better handling when there's no event between (s, t]

2008-10-14 Arthur Allignol <arthur.allignol@fdm.uni-freiburg.de>
	
* Bug correction: now works when there is only 1 transient state.
* Modification of the part which transforms the data into counting process
* Modification of the C++ routine
	that is now faster nd computes the increments
	of the Nelson-Aalen estimator
* Add a plot function
