Formatting error in markdown documentation for programming

[psfales]

Current Behavior

There is a formatting error in the documentation for the programming frame work at
https://github.com/iNavFlight/inav/blob/master/docs/Programming%20Framework.md

The description for operation 50 (Delta) wants to say |A|>=B, but since | is a markdown character it looks different in the output

Steps to Reproduce

View the page at https://github.com/iNavFlight/inav/blob/master/docs/Programming%20Framework.md

Expected behavior

The description of the operation should be visible

Suggested solution(s)

Escape the markdown characters

Additional context

As a side note, I found this confusing, as I first thought |A| meant "Absolute value of A" rather than "The amount that A changed in the last 100msec. Another fix would be to write it differently, perhaps Delta(A)

[sensei-hacker]

Done.
