  Description   : A convenience function that creates an EPS and a PNG output
                  file with one or two logos.
                  The function performs a system call to "convert"!
  Parameter     :
    motif1      : First motif. Can be NULL.
    label1      : Label of the first motif (= logo title). Can be NULL.
    motif2      : Second motif. Can be NULL.
    label2      : Label of the second motif (= label for x-axis). Can be NULL.
    errbars     : print error bars if true
    ssc         : use small sample correction if true
    height      : height of logo in cm.; use default if 0
    width       : width of logo in cm.; use default if 0
    shift       : Shift of the first logo relative to the second logo. Can be 0.
    program     : name of program to print in fineprint in lower left 
    path        : Path for the output file WITHOUT an extension.
                  Since an EPS and a PNG file are created, the path should
                  contain only the output folder and the logo name but no
                  file extension. See example.
    make_eps    : make a EPS logo
    make_png    : make a PNG logo
  Global Var.   : Uses GS_PATH 

  Example       :
    CL_create2(motif1, "Motif", NULL, NULL, false, false, 0, "MEME (no SSC)", 
        "myfolder/logo", true, true);
