CHANGES IN VERSION 1.10.0 
------------------------------

NEW FEATURES

    o Add function mapGenomeBuilds() that maps between UCSC and Ensembl
    builds. 

    o Add function genomeBuilds() that list all the available UCSC or Ensembl
    builds for a given organism[s] that can be used in mapGenomeBuilds() 

    o Add listOrganism() that list all currently available organism[s] included
    for use in genomeBuilds()

DEPRECATED AND DEFUNCT

    o After being deprecated, the species() method for GenomeDescription objects
    is now defunct

MODIFICATIONS

    o Zebra finch is removed as option for
    fetchExtendedChromInfoFromUCSC() as it is not support yet

    o keepStandardChromosomes() chooses first style when multiple are matched

BUG FIXES

    o Fix WARNING occuring when determining style in keepStandardChromosomes() 


CHANGES IN VERSION 0.99.7
----------------------------------

MODIFICATIONS

   o rename:
     isSupportedSeqnames -> .isSupportedSeqnames
     supportedSeqnameStyles -> .supportedSeqnameStyles
     supportedSeqnameMappings -> .supportedSeqnameMappings
     isSupportedSeqnamesStyle -> .isSupportedSeqnamesStyle


CHANGES IN VERSION 0.99.6 
----------------------------------

NEW FEATURES

   o add new functions()
     seqnamesInGroup which will take a character vector of chromosomes and 
     return the chromosomes specified by the group parameter supplied by the 
     user. The user can also give the species and the style.
     seqnamesOrder() internally calls Herve's function makeSeqnameIds()
   o add seqnameStyles generic and method from GenomicRanges

MODIFICATIONS

   o rename:
     testSeqnames -> isSupportedSeqnames

   o move SeqnamesStyle generic from GenomicRanges and define a new method which
     works on a character vector.
         
DEPRECATED AND DEFUNCT

   o deprecate listAllSupportedStylesBySpecies(), 
     listAllSupportedSeqnameStyles(), supportedOrganisms()
     supportedSeqnameMappingsWithGroup()
       
   o deprecate supportedSeqnameMappings(), supportedSeqnameStyles(), 
     isSupportedSeqnamesStyle(),issupportedSeqnames()


CHANGES IN VERSION 0.99.17

MODIFICATIONS

   o keepStandardChromosomes: Make 'species' argument optional and remove 
     'style' argument.

     extractSeqnameSet -> extractSeqlevels
     extractSeqnameSetByGroup -> extractSeqlevelsByGroup
     findSequenceRenamingMaps --> mapSeqlevels
     seqnamesInGroup --> seqlevelsInGroup

     supportedSeqnameMappings, findSequenceRenamingMaps, 
     supportedSeqnameStyles,  supportedSeqnames, 
     extractSeqnameSet, testSeqnames, isSupportedSeqnamesStyle,
     listAllSupportedStylesBySpecies, listAllSupportedSeqnameStyles.
        
   o makeSeqnameIds moved from GenomicRanges
