Description:

Specialization of abstract interface class ConfigurationPlugin, retrieves configuration data from the system environment.

Its priority value usually is Priorities::Environment , which is higher than Priorities::Standard but lower than Priorities::CLI .

Variable categories are used as a prefix together with an underscore '_'. This means, if variable LOCALE in category ALIB is accessed, the environment variable ALIB_LOCALE is read.

Category and Variable names are insensitive in respect to character case.
