It adds an initial Biojava manager with a minimal amount of ported functionality and fixed an issues in that bridgedb.guessIdentifierType() did not always provide expected output. The following new functionality was ported in this release, along with the Bioclipse domain objects IDNA, ISequence, IProtein, and IRNA:

Bioinformatics managers

• biojava.DNAfromPlainSequence(dnaString)
• biojava.DNAfromPlainSequence(dnaString, name)
• biojava.proteinFromPlainSequence(proteinString)
• biojava.proteinFromPlainSequence(proteinString, name)

Cheminformatics managers

• pubchem.downloadAsString()
• inchi.options()
