- Merge pull request [97](https://github.com/mozilla/node-convict/issues/97) from yoz/cjson-0.3.2
Update cjson dependency to 0.3.2
- Update cjson dependency to 0.3.2
This removes the transitive dependency on 'jsonlint' (in favor of json-parse-helpfulerror), which avoids its problems with unstated depdendencies on 'file' and 'system'.
- Coerce values loaded from a file
Previously values were coerced if added through
set(), command line arguments or env arguments.
Added the schema to the recursive overlay function
so that values added through load() and loadFile()
are also coerced.
Corrected a test to reflect this.
