NOTE: All JSON numbers are converted to float fields.
JSON strings and booleans are ignored unless specified in the tag_keys or json_string_fields options.
The time layout that should be used to interpret json_time_key.
The time must be "unix", "unix_ms", "unix_us", "unix_ns", or a time in the "reference time".
To define a different format, arrange the values from the "reference time"
in the example to match the format you will be using.
For more information on the "reference time", visit https://golang.org/pkg/time/#Time.Format.
Returns the relative, descendent directory path between this module and other.
Throws if no such path exists.
For example, if module mod1 has path /dir1/mod1.pkl, and module mod2 has path /dir1/dir2/dir3/mod2.pkl,
then mod1.relativePathTo(mod2) will return List("dir2", "dir3").
A common use case is to compute the directory path between a template located at the root of a hierarchy
(say rootModule.pkl) and the currently evaluated module (accessible via the module keyword):
The JSON data format parses a JSON object or an array of objects into metric fields.
