…rride PailtoString() method for nicer printout

Locally I have a gradle build setup instead of sbt, so it doesn't give me classpath related errors as above, so disregard this pull request for the time being |

TypedRecordOutputStream.writeObject(obj);
should check type of object being written to Pail.
Pail.toString() is also overriden to print Pail info more nicely (not just for this issue of course).
Result is following exception message:
Exception in thread "main" java.lang.IllegalArgumentException: Cannot write object SomeString of invalid type (class: java.lang.String) to pail: Pail{root='/marztest/bigdatalab/new', spec={structure=com.marcinko.bigdatalab.utils.pail.graph.DataPailStructure, args={}, format=SequenceFile}, fs=org.apache.hadoop.fs.LocalFileSystem@6fe78c96}
