Create a reference implementation using Fit SDK library for validation

[stadelmanma]

Having a very basic reference implementation that I can compare my library’s output against would make fuzzing out bugs and corner cases much easier. It probably makes sense to output data in something easy to work with on the CLI, maybe a tab-delimited file similar to the FitToCSV tool output.

The CPP code looks like a good start for this. Yeah We’ll want to track the message name & number, and then inside that the field name, number, value and type.

Whatever format the implementation creates we’ll need it to be:

• easy to read
• easy to view a diff of (e.g. using git diff)
• simple to generate (no extra libs needed)
• easy to parse

The first two reqs mean we will want to keep line lengths reasonable which excludes JSON lines. True JSON is also not exceptionally easy to parse or generate without pulling in extra libraries anyways. For parsing ease we want to avoid multiple spaces as a delimiter; single tabs and and new lines are fine.

A basic indented structure comes to mind:

HEADER
:TAB:header field
…

MesgNum,Message Name
:TAB:FieldNum,FieldName,FieldType,Value
…
