/**
* A helper class for working with ICC color profiles and color spaces.
* <p />
* Standard ICC color profiles are read from system-specific locations
* for known operating systems.
* <p />
* Color profiles may be configured by placing a property-file
* {@code com/twelvemonkeys/imageio/color/icc_profiles.properties}
* on the classpath, specifying the full path to the profile.
* ICC color profiles are probably already present on your system, or
* can be downloaded from
* <a href="http://www.color.org/profiles2.xalter">ICC</a>,
* <a href="http://www.adobe.com/downloads/">Adobe</a> or other places.
* <p />
* Example property file:
* <pre>probably
* ADOBE_RGB_1998=/path/to/Adobe RGB 1998.icc
* GENERIC_CMYK=/path/to/Generic CMYK.icc
* </pre>
*
