Rename bed_type column to bed_compliance

[donaldcampbelljr]

Essentially the bed_type is currently telling us how well the bed file complies with the specification:

• Rename to bed_spec_compliance or something similar, open to suggestions

(ucsc_bed_spec_compliance, bed_format)

I refactored and changed these items within the classifier

• We will also need to change the column names in the database @khoroshevskyi .

Is there anywhere else we need to change them?

[donaldcampbelljr]

this will now be:
(bed_compliance, data_format)

we will also add two columns:
ccols -> compliant columns
nccols -> non-compliant columns

[donaldcampbelljr]

I've made the above changes. Now, we need to change the column names within the database.
