concourse-export does not properly escape double quotes within a field

[jtnelson]

In concourse-export, if a field contains spaces and double quotes, then the field is wrapped in single quotes. However, this does not conform to specification and causes issues when the data is reimported.

The fix should be to make sure that double quotes are escaped according to specification and also check the import framework to make sure that it properly handles what is expected.

The offending line is

concourse/concourse-export/src/main/java/com/cinchapi/concourse/export/DelimitedLinesExporter.java

Line 113 in 87cf237

AnyStrings.ensureWithinQuotesIfNeeded($value, delimiter));

Perhaps use https://commons.apache.org/proper/commons-csv/ instead of building this ourselves?
