test commit for alangner branch

Changed small thing in GetLLM to check alangner branch on afs.
Merge branch 'master' into alangner
Extended phase directory in GetPhases()

GetPhases() calculates now phase advances between 7 consecutive BPMs.
This will be used for the new Beta from Phase algorithm.
Phase advance from previous calculation are not yet removed and 
also still kept in phase dictionary (to be cleaned later).
Separated functions for beta from phase calculation

For the beta from phase calculation, three functions are
introduced for the three different cases of the probed BPM location.
(Left/right or in the middle of the two other BPMs)
Extended phase advance calculation (AC)

Phase advance for 7 consecutive BPMs are now calculated in
GetFreePhase_Eq() and stored in the existing variable 'result'
Merge branch 'master' into alangner
Added docstrings to some functions
Merge branch 'master' into alangner
New algorithm in current GetLLM implemented

Improved robustness of GetLLM

Does not crash if you run only with either linx or liny file. Writing
files are extracted into a finally block. 'higher_order' functions are
not crashing if only linx or liny file is given.
Made the reading of the files safer in GetLLM
Omitted creating empty files

Files which have no data rows will not be printed. getIp.out has no
default values([0,0,0...) anymore.
Adapted GetLLM_valid.py
Inserted check in filecheck.py if files which will be compared are
valid(not empty).
Inserted check if parsed files available in GetLLM

Additionly replaced except: with except KeyError in interaction_point.py
Renamed modelIntersect

Utilities.bpm.modelIntersect() was changed to model_intersect() to
follow the style guides. Changed corresponding methods in getsuper.
Changed dir comparison and removed bug

Comparing all dirs in the given output folders. Before the diff_files
were only related to the 'top folder' but not to subdirs.
Corrected phase advance for last monitors in new algorithm

Note that the phase advance between the last monitor and the first
monitor should be find by taking into account the fractional part of
tune.
