Format Tick Labels (Extended)

Replace Tick Label with LaTeX compatible Objects. Extends file 15986 created by Alexander Hayes.

Will replace axes tick labels with formatted text objects that can include both Tex and LaTex interpreted strings. Primary example is to add degree symbols to labels. Inputs can be a cell array of strings or a single string to be appended to the end of each of the current labels. Header documentation includes several examples. Labels can also be rotated.

Introduces a distinction between offsets for the horizontal axis offsetx and for the vertical axis offsety. It took 2 minutes to modify the original file, so credit must go to Alexander Hayes. Any errors are mine, of course.
