Bundler::GemHelper.install_tasks
# Requires Bundler and adds the 
#build, install and release 
#Rake tasks by way of calling Bundler::GemHelper.install_tasks. 
#The build task will build the current version of the gem and 
#store it under the pkg folder, the install task will build 
#and install the gem to our system (just like it would do if we 
#gem install'd it) and release will push the gem to Rubygems for 
#consumption by the public.
