changes in version 1.7.1 (2011-1-12)
	* added pub2date to retrieve publications details from PubMed.  The
	pubmed table was created using pub2date.
	* added acc2date to retrieve release dates from the Sequence Revision
	History. The revhist table was created using acc2date.
	* added functions to parse month or year from release dates
	* removed the gold dataset since GOLD is no longer freely
	available (email 3/2011 - "we cannot support redistribution in any
	form"). HMP uses GOLD data so I removed that dataset too.
	
changes in version 1.5.6 (2010-10-14)

	* updated biocViews in DESCRIPTION
	* fixed updatelproks to replace latin characters before removing
	extra spaces (which caused an error) 
	* set released dates with 2000-1-1 to NA in lproks

changes in version 1.5.4 (2010-8-2)

	* deleted Sweave file about Entrez queries (remote queries were
	causing frequent errors in package builds)

changes in version 1.5.3 (2010-7-30)

	* moved sort01 routine before option to limit matrix to 50 rows in
	image2
	* fixed term2summary.  Searches in genome projects may return
	matches but not "genome sequencing" types, so this caused an 
	unhelpful error message.

changes in version 1.5.2 (2010-5-18)

	* added image2 to plot a matrix
	* fixed error in plotby.  Previously limited to 10 groups.
	* fixed update(lproks) after refseq ids were added to all three
	lproks tabs and genbank accessions were added to in progress tab
	* fixed update(virus) after modified date added to table

changes in version 1.5.1 (2010-4-23)

	* removed the wgs dataset.  The lproks table again reports release
	dates for assembly genomes (no release dates were added between
	9/15/09 and 4/15/10)

changes in version 1.4.0 (2010-4-13)

	* fixed the main url (eutils.ncbi.. not www.ncbi) and added tool
	and email options to E-utility scripts (now required by NCBI).
	* added details to genomes-update about reporting counts of new
	IDs added and old IDs removed.

changes in version 1.3.1 (2010-4-11)

	* added print.genomes method to print the first few rows and
	columns of a genome table (also reordered the datasets so
	id, name, status, and released is in first 4 columns)
	* improved messages for updating genomes.  Now the number of new
	project ids added AND old projects ids removed is reported
	* modified package to import XML package (no longer depends on
	XML)
	* added subset.genomes and [.genomes to extract parts of a genome
	table (and preserve some genome class attributes and not others)
	* added latin2char function to replace a few latin characters in
	NCBI tables with ASCII. Now R CMD check runs without the "Portable
	packages use only ASCII characters in their datasets" warning
	* added new summary methods for tables without status column

version 1.3.0 uploaded to BioConductor for review (2010-2-19)
