Gem setup and basic coding

tables generated with correct associations
there's a model with no gem call
some models have their own methods to use
name is the only default method
--should I act an exclude also?--
caught some nil cases in gem code

finished setting up gem for install

changed version of rails on gemfile to make compatible
added summary and description on rakefile
fixed some variable names on config and other files
added option to skip attributes

the args hash for the word cloud now has a skipped_attributes key
  its value will be an array containing symbols for the model's
    string attributes we do not want as part of the result
added new parameter to word_cloud

now it defaults to a single string for the results
it can take the symbol :array to give results as an array
Prepare for 0.0.1 release
