fparser: a pedestrian m-file parser and tokenizer

lists ML-tokens and constructs (function, var, struct assignment) in a m-file or from a command line

Description

FPARSER parses a M-file or command line
and list tokens and constructs:
- functions/keywords
- variables/constants
- struct field assignments

see the accompanying published m-file for an example

The concept of parsing a MATLAB file is new to me. I guess that can help programmers to analyze the cost of the script, in a manner of minimum number of variables, functions, etc...Anyway, I have to parsing this great work first.

The file is well commented, some lines are cryptic, but thats good for learning new programming styles :-) Excellent tool for compiling a documentation of your project.
Some remarks:
variable i: (output of the fparser):
i > 11 built-in (C:\install\Matlab\toolbox\matlab\elmat\i)
That is true, but in my context I use it exclusively as a counter (for i=1:N)
And one question: what exactly represents:
 .nstok nr of STRUCT.FIELD assignments ?
Thank you.

Excellent work! Here's a fresh bug report:

Code 'idx>0' gets tagged as a field rather than an expression.

Very useful function. thanks.

Found 1 bug. Comment on lines after a function "end" seem to cause an error.
