Detailed Description

Provide access to configuration information for a given package called 'name'.

To use it, just instantiate an object of this type. All lookups will be prepended with the 'name' given.

Config config("MyTest"); std::string value = config.get("MyValue","MyDefault");

will look up 'Mytest.MyValue: ...' in the configuration file.

The configuration file is searched in the following places:

• ${CAFE_CONFIG} if the environment variable is set
• ./cafe.config if it exists
• ${SRT_PRIVATE_CONTEXT}/cafe.config
