/**
51
 * Creates a database dataset based off of a spec string.
52
 *
53
 * This spec class requires a list of databases to be set to the object before
54
 * it can return a list of databases.
55
 *
56
 * The format of the spec string is as follows:
57
 *
58
 * <db label>:<schema>:<tables>
59
 *
60
 * The db label should be equal to one of the keys in the array of databases
61
 * passed to setDatabases().
62
 *
63
 * The schema should be the primary schema you will be choosing tables from.
64
 *
65
 * The tables should be a comma delimited list of all tables you would like to
66
 * pull data from.
67
 *
68
 * The sql is the query you want to use to generate the table columns and data.
69
 * The column names in the table will be identical to the column aliases in the
70
 * query.
