Question about Circuit.ToJSON() output when overrides to LineCode, XfmrCode, or other codes exist for a component

[John-Boik]

In an OpenDSS file, an entry for a new line, transformer, or other component can reference a code (e.g., a LineCode) and then override values in the code by specifying new values in the definition of the component, after reference to the code. For example:
New Line.lineA .... Linecode=LineCodeB, EmergAmps= 410
In this example, the line's EmergAmps value will be 410, regardless of what LineCodeB specifies. My question is, can I trust that the output of Circuit.ToJSON() will always capture any overridden code values for a component?

In the given example, this would mean that the JSON output for a line specified as:
New Line.lineA .... EmergAmps= 410, Linecode=LineCodeB
would reflect the value of EmergAmps as given in LineCodeB, and the one used in any analysis by OpenDssDirect. I just want to verify that this is the way the ToJson function works and the way the JSON schema is used, for any component.

Kinda: if the values are present, they should be ones from the LineCode, but it also omits previously set values.
When you set LineCode=..., it replaces most of the current values in the Line. A lot of properties are marked as unset when you specify a LineCode, e.g. if you previously provided R1 and X1 (or a Geometry and Spacing pair), they should be omitted from the output (either JSON or DSS code from the Circuit.Save() function) in the default settings (without the compatibility flag NoPropertyTracking).

For New Line.lineA .... EmergAmps= 410, Linecode=LineCodeB, it should list the value copied from LineCodeB, currently.
I made a note to check if we can omit EmergAmps (also NormAmps and Ratings) from the output in this case (IIRC, there was a specific detail about this).

Note that FaultRate, pctPerm, and Repair are not copied from the LineCode. Just right now, I marked those as deprecated and unused. Pre-2014 versions of OpenDSS copied those values from the LineCode to the lines, but they are not used anywhere since then (i.e., users need to provide those values individually on each Line).

Most of these changes I'm mentioning should be included in the next release in the next few days and should be reflected later in the docs in our site. I wasn't expecting the release of OpenDSS v10.0.0.1, so now I'm finishing porting the new code, especially the new WindGen. We do a lot of refactoring and cleaning up while porting.
