public class Properties

implements Comparable<Properties>, Mergeable<Properties>, CloneHandler<Properties>
```
Enhanced java.util.Properties class.
Date types are stores as follows:
- time: FORMAT_TIME
- date: FORMAT_DATE
- date/time: FORMAT_DATETIME
Colors are stored as hex string, i.e., "#RRGGBB" with all three values as hex values. The following string representations of colors are supported as well (case-insensitive):
- black
- blue
- cyan
- darkgray
- darkgrey
- gray
- grey
- green
- lightgray
- lightgrey
- magenta
- orange
- pink
- red
- white
- yellow
The read(String) and read(String, List) methods also look for platform-specific properties files using platform-specific extensions: EXT_LINUX, EXT_ANDROID, EXT_MAC, EXT_WINDOWS.

```
public static Properties read(String name)

Not to be confused with load(String). Also looks for environment variables with a semi-colon separated list of key=value pairs to override the values loaded from the .props file(s). E.g., for "adams/core/io/FileUtils.props" the environment variables "adams_core_io_FileUtils" or "ADAMS_CORE_IO_FILEUTILS" can be used.
    
    Parameters:
    
    name - the location of the resource that should be loaded. e.g.: "adams/gui/Something.props".
    
    Returns:
