Boston Housing re-uses attribute names in different type fields

[hayesall]

It would probably be good to revisit this dataset:

• Create standard cross validation folds
• Make datasets with relational_datasets.from_numpy

Currently reusing attribute names in different type fields, e.g.:

age(id100,1).
age(id101,2).
age(id10,2).
age(id102,4).
age(id103,2).
% ...
b(id97,2).
b(id98,1).
b(id99,2).
chas(id1,0).
chas(id10,0).
chas(id100,0).

Causes issues like the following:

Deprecated Boston Housing in #23.

This may still cause problems, but I won't fix this.
