Graphically display the 'branch' structure of a struct variable

Recursive function designed to display the 'branch' structure of struct variables.

Welcome to my first post!

Recursive function 'structstruct.m' accepts a single input of any class and outputs ASCII to the command window. Currently no function outputs.

For non-structure input, structstruct displays the class and size of the input and then exits. For structure input, structstruct displays the fields and sub-fields of the input in an ASCII graphical printout in the command window. The order of structure fields is preserved.

Has header and commented 'help' text with INPUT/OUTPUT info. Code is decently commented.

I designed this function so I could easily explore the structure of a struct variable without 'digging' through all the fields in the Variable Editor. It serves its purpose very well, but there are surely areas for expanded/improved functionality that I'm not seeing...

Comments and suggestions welcome!
