## Usage

Something like this:
```ruby
	require 'rika'

	parser = Rika::Parser.new('document.pdf')

	# Return the content of the document:
	parser.content 

	# Return the media type for the document:
	parser.media_type 
	=> "application/pdf"

	# Return the metadata field title if it exists:
	parser.metadata["title"] if parser.metadata_exists?("title") 

	# Return all the available metadata keys that can be read from the document
	parser.available_metadata

	# Return only the first 10000 chars of the content:
	parser = Rika::Parser.new('document.pdf', 10000)
	parser.content # 10000 first chars returned

	# Return content from URL
	parser = Rika::Parser.new('http://riakhandbook.com/sample.pdf', 200)
	parser.content

	# Return the language for the content
	parser = parser = Rika::Parser.new('german document.pdf')
	parser.language
	=> "de"

	# Check whether the langugage identification is certain enough to be trusted
	parser.language_is_reasonably_certain?
