parseargs - A very flexible inputs parser

Very flexible inputs parser. Parsing name-value pairs with default property easily.

Useful when a function requires multiple options.

PARSEARGS Set name-value pair arguments with default property easily.

The basic usage is like other similar functions in FEX, e.g., parseargs (Malcolm Wood), parse_pv_pairs (John D'Errico).

My parseargs can handle flexible input arguments (e.g., name-value pairs, a struct followed by name-value pairs, two struct, ...).

Besides, it allows user to control the parsing behavior, such as

1. ['-checkcase'] whether parameter names are case-sensitive or not,
2. ['-partial'] whether parameter names can be partially matched or not,
3. ['-fix'] whether unmatched parameters can be kept or not,
4. ['-checkclass'] whether data type can be changed or not,
5. ['-checksize'] whether data size can be changed or not,
6. ['-verbose'] whether any warning is shown or not.
