# Creates instance methods which call class methods. These are delegations rather than aliases.
# Expects a hash of classes/modules of the instance method mapped
# to a hash of the class methods and the instance method names.
# For example, the hash {"MyDate"=>{'Date.today'=>'t'}} would create a MyDate.t instance method
# which directly calls Date.today.
