Standardization of getllm-output column-names

[JoschD]

If you see some, that don't make sense, add to this issue. One day we can change them all:

everywhere:
MDL, STD etc. either in front or after the name.
(as of now, MDL is after, everything else in front... most of the time)

getcouple.out:
FWSTD1 -> STDF1001W
FWSTD2 -> STDF1010W

Everything in ndiff:
A massacre of
upper-case vs. lower-case,
_m vs. MDL vs. _model,
re vs. r vs. R,
im vs. i vs. I,
e vs. ERR,

I am very happy to contribute to this list. Unfortunately this would create huge changes to the GUI code without any real gain.

I already brought up this issue for getbeta*.out, getampbeta*.out, getphase*.out in order to better reflect actual values (statistical / systematic errors can't be distinguished in the analytical N-BPM method, column names weren't consistent for 3-BPM and N-BPM method).

My suggestions to this issue:

• remove completely statistical and systematical error columns in getbeta*.out. N-BPM doesn't distinguish between them and 3-BPM only includes statistical errors. So we could just keep ERRBET
• change PHASE in getphase*.out to DELTAMU or DMU since it is the phase advance between the two elements and not the phase advance to the origin.
• in getphase*.out, clear up NAME, NAME2 but S, S1.
