# Create a new configurable extension called +name+.
#
# Three methods will be defined on the calling object which allow to use this configurable
# extension:
#
# configurables:: Returns a hash of hashes that is used to store all configurables of the
# object.
#
# <name>(ext_name):: Return the configured extension +ext_name+.
#
# add_<name>(ext_name, data=nil, &block):: Define an extension +ext_name+ by specifying either
# the data as argument or by using a block.
