#Installing Parser
Download parser from here: http://nlp.stanford.edu/software/lex-parser.shtml#Tools
Set export STANFORD_MODELS="/usr/local/Cellar/stanford-parser/3.5.2/libexec/stanford-parser-3.5.2-models.jar"
(Or your path to models.jar) on your bash_profile
Set export CLASSPATH="/usr/local/Cellar/stanford-parser/3.5.2/libexec/stanford-parser.jar":"/usr/local/Cellar/stanford-parser/3.5.2/libexec/stanford-parser-3.5.2-models.jar"
(Not sure if the second path is necessary but I am afraid to break it)
update bash_profile with source ~/.bash_profile
Try to run the example.
