v0.004

    For conditional designs add optional block oligo region overlap value.
add Human as a valid species, and chromosomes 20,21 and 22
use species design parameter when setting up EnsEMBL util, do not hard code Mouse
add default assembly for Human, make species a command line option, still defaults to Mouse
add human base chromosome directory information, and builder method for working out which base chromosome directory is needed
fix EnsEMBL role tests, and add and test new exon adaptor
add species and assembly to design parameters file in tests
remove chromosome and strand attributes from OligoRegionCoordinates role and add pack to specific command roles
fix unrecognised species error test, switch from Human, which is now valid, to Unicorn, which sadly will never be valid
when trying to find design parameter look first in design parameters hash, if not there see if a attribute of that name exists and return that
add delete-exon-design to multiple design wrapper script
add command to create design by targeting a specific exon
perlcritic fixes
add test for del-exon-design command
pick working target to test del-exon-design command
