Load-Settings

=============

When you design a program with a bunch of parameters to tune, you don't want to hard code the parameters in code because that means you need to recompile the porgram everytime you try a new parameter. Instead, all tunable parameters should be saved to file and could be updated in that file. 

The API is simple to use. All you need to provide is a filename where you want to save the settings and a set of parameters and their corresponding names. 

```

Seetings::( Filename, MakeParam(Parameter, Parameter name) );

```

1. A xml file will be automatically generated on the first run of the program with a list of all parameters and their default values.

2. All parameters in the xml file can be updated and the program will load new values from the xml file. If a parameter is update, a *updated* tag added behind hte parameter. 

3. The API function supports an arbitary number of parameters. 

4. C++11 and [boost libraries](http://www.boost.org/) ae required. 

Sample code

-----

```

int main(){

    // Parameters

    bool  b = false;

    int   i = 2000;

    float f = 1.73e3f;

    // Settings file name

    string filename = "settings.xml";

    Settings::load( filename, MakeParam(b, "boolean"),

                          MakeParam(i, "integer"),

                          MakeParam(f, "float") );

}

```

Example output

------

The console output: 

```

Parameters are set to the following: 

           boolean: 1 (updated)

           integer: 2000

             float: 1.73e3f

```

A *settings.xml* file: 

```

true

2000

1730

```
