3.1.5 -- added forma. to ranks, tests for species epithets with apostrophe

3.1.5 -- updated depenencies

3.1.4 -- added files generated by tt to repository

3.1.3 -- removed dependency on jeweler

3.1.2 -- fixed problems with infraspecies epithets starting with fo,
for example Peristernia nassatula forskali Tapparone-Canefri 1875

3.1.1 -- fixed problem with names ending on sp

3.1.0 -- added surrogates: Genbank, Barcode of life names.
Also cf., sp. spp are flagged as surrogates

3.0.1 -- updated gems

3.0.0 -- removing support for ruby 1.8.7, making biodiversity gem be the same
as biodiversity19, deprecating biodiversity19. A few newly discovered bugs
are fixed.

2.1.0 -- added ScientificNameParser.version method

2.0.0 -- backward incompatibe change in parserver, therefore new major number.
In parserver removed option --output=canonical_with_rank, instead added -r
option which allows to have canonical with rank with either json or canonical
outputs

1.2.0 -- changed method invocation signature ScientificNameParser.new
Now it can take options

1.1.3 -- added 'fo' as rank

1.1.2  -- static method for fixins all-caps canonical names, fixing caps
for authors words, ampersand instead of 'et' in normalization

1.1.1  -- more multi-uninomials cases, expanded viruses detection, added
abbreviated genera and a few small fixes

1.1.0  -- added multi-uninomials, fixes in identification annotations (aff.,
cf., sp. etc), bug fixes, more robust salvage mode

1.0.17 -- fixed a bug which prevented all diacritics be converted correctly

1.0.16 -- dirty mode now converts ë to e

1.0.15 -- additional rules added for names ending with ssp. sp sp. and cf.

1.0.14 -- canonical forms had allowed ë as a character until now. After this
version the only utf-8 character allowed in canonical forms should be the
multiplication sign for hybrids.

1.0.13 -- canonical forms for cf. aff. qualifiers are modified: canonical for
'Aus cf. bus' is now 'Aus bus'; canonical for 'Aus aff. bus' is now 'Aus'.
Ranks at the end of the name like 'var', 'ssp', 'spp' are considered junk and
are ignored

1.0.12 -- bug is fixed which prevented 'Cucurbita pepo' be parsed correctly,
f., forma, fr. are now treated as any other ranks.
