initial experiments with parsec as an information extraction dsl
simpler types
simple examples of Parsec for information extraction
version bump to 0.2.0.0
added note about SO q/a relevant to custom parsec parsers
added case insensitivity options to the Literal Tagger
updated the LiteralTagger to modify the tokenizer to account for multi-word terms that are specified as individual linguistic components.  eg: \'United States\' might be tagged as a proper noun, and may more easily be tokenized as one token.
removed some unnecessary cpp cruft
added posPrefix to make it easier to define simple equivelance classes of POS-tagged tokens when parsing.  For example, to parse all common nouns.
Threaded the mkTagger case sensitivty settings through to the tokenizer in the LiteralTagger
wrapped up initial parsec integration for extraction patterns
added tests for the information extraction module
