/**
 *  Use mapKeys to convert object keys to another format using the specified conversion function.
 *
 *  E.g., to deep convert all object keys to camelCase:  mapKeys(myObj, _.camelCase, true)
 *        to shallow convert object keys to lower case:  mapKeys(myObj, _.toLower)
 *
 *  NOTE: This mutates the object passed in for conversion.
 *
 *  @param target - {Object} The object to convert the keys
 *  @param converter - {Function} The function that converts the object key
 *  @param deep - {boolean} Whether to do a deep object key conversion
 *  @return {Object} - the object with the converted keys
