Get-TlsEccCurve documention somewhat sparse

The documentation for the Get-TlsEccCurve cmdlet is virtually non-existent, there is no synopsis, no examples and no clue as to what IT Pros should use this cmdlet for.

Is there some further documentation? If so, I'll happily knock together a P/R to add this information.

Also: other cmdlets in the TLS module are equally as sparse.
