@m4dcoder : How do I specify an enum?

[m4dcoder]

{
enum: ['fe', 'fi', 'fo', 'fum']
}

1. Need a README.md explaining how to hook this up with JIRA (else we forget ourselves).
2. Once we have default parameters in place, can we suggest in "README" to go set/update defaults in jira.create_issue JSON?

If you add RCA_CERT_FILE to exception the user will get an idea where the file should be. "Cert file not found fro JIRA OAuth at " + RCA_CERT_FILE
