zeroj needs to run wignercycle when database not available. threej has similar problem. sixj as well

[AlainPlattner]

zeroj line 68:

  error('Insufficient bandwidth for database')
  % HERE WE SHOULD RUN WIGNERCYCLE

Need to make it automatically run wignercycle to improve ease of use. Or at lease print out a warning: please run wignercycle(xxxx)

[AlainPlattner]

threej has a similar problem on line 82 and 85.

[AlainPlattner]

Also in gammap line 258:
when we call sixj without having yet calculated any wigner 6j symbols before, then the function crashes because the list of databases is empty

[AlainPlattner]

And even if there is a 6j database already, I get an error in wignercycle

Undefined function or variable "fid1".

Error in wignercycle (line 212)
fwrite(fid1,C,fmt1); % The column number, "C"

Error in sixj (line 108)
wignercycle(L,6);

[AlainPlattner]

It seems as if there are issues with wignercycle, zeroj, threej, and sixj.
To recognize and iron out all issues, I recommend to try and run the programs with an empty /WIGNER directory.

Frederik should be the one to decide what to do with this, but I will just add that I know there are some things in three and sixj that will purposefully break because he wants people to use wignercycle instead to make the databases. I have not used these much, so he should tell you his "vision".
