Added plugin to create a data dictionary similar to the old way. Give it
3 files of csv lines (colName,dataType) and it will create the
dictionary. Still need test file.
Fix to shifu-core to throw runtime exception if attempt to create a
model using the same name as an existing model.
Creation of new plugin createdd that will create a DataDictionary based
on information in a text file. Will otherwise default all values to
string, continuous.
added the createdd plugin to the main pom.xml file so travis will
compile and test it.
Added test. Moved things around in json file
added eBay Software Foundation license info
