Process named Arguments

Assigns named arguments passed to your function to local variables (as in plot(), etc.). The name of the argument is the name of the local variable in your function.

Example: inputfun('prompt', '>', 'defval', 5.1, 'timeout', 5);

This is the same idea as Matlab's inputParser, but with a focus on being really simple and easy to use. Other implementations of this idea on File Exchange require a lot of lines of code to set this up, where as my code just requires one extra function call near the top of your function.

Usage:
(1) in your function, define local variables with their default values;
(2) call procArgs(varargin)

Minimal error checking: requires that all passed variable names match already defined variables in your function. It would be pretty easy to add type checking if you wanted it (I don't, particularly).

Example:

function test(varargin)
name = 'John';
age = 32;
procArgs(varargin)
fprintf('name=%s, age=%i\n', name, age);

%% example calls
test('name', 'Amber'); % prints Amber, 32
test('age', 99); % prints John, 99
test('Ages', 0); % error, will report that Ages is not defined.
