* @brief A simple command-line argument parser based on the design of

* ArgumentParser is a simple C++ class that can parse arguments from

* anyone who has used python's ArgumentParser:
|

* \code
|

* // create a parser and add the options
|
||||
* ArgumentParser parser;
|
||||
* parser.addArgument("-n", "--name");
|
||||
* parser.addArgument("--inputs", '+');
|
||||
*
|
||||
* // parse the command-line arguments
|
||||
* parser.parse(argc, argv);
|
||||
*
|
||||
* // get the inputs and iterate over them
|
||||
* string name = parser.retrieve("name");
|
||||
* vector<string> inputs = parser.retrieve<vector<string>>("inputs");

* \endcode
