improved commenting on randforest.py mainly
Created Help_Explore_Explain.py file for everyone to
add their favorite learnings, hints, help , etc.
Improved commenting on predict.py
Started a new file called higherlevel.py, defined a very powerful filtering algorithm that supercedes most of what is in predict.py.
Created file PrepareTitanicData, which does what it says.
function titandata(dataset) returns regularized, floated array with useless stuff deleted and placeholder values for missing data. Modified higherlevel.py a bit.
Added a bunch of analysis to higherlevel. Can now filter by any features, even continuous age and fare ranges.
Improved PrepareTitanicData to include the option of getting
test data in same format as train (called test8).
Created predictions.py, which has several functions that create predictions and compare them. Further analysis added in higherlevel.py.
Created prediction_file_writing_codes.py.
Wrote randomforests() function in predictions.py.
New csv prediction files added
