Robin Anil updated MAHOUT-157:
------------------------------

    Attachment: MAHOUT-157-Oct-1.patch

Finished Sequential version of FPGrowth. May need some more documentation and cleanup

run ParallelFPGrowth in examples
with following settings

s = min support
h = max size of heap
g = number of groups (works for parallel version)

-i /home/robina/Desktop/accidents.dat -o output -s 3 -h 100 -g 1000 -method sequential

accidents file is a transaction list with each line as a traction with features delimited by comma or tab
You can download a dataset from here http://fimi.cs.helsinki.fi/data/
the dataset needs to be converted into comma separated or tab separated. (Ensure there are trailing commas at the end of the line)

the output file will have the top h patterns for each frequent feature
