Allow attach/detach db to a IModel connection to allow combine data from two or more files.

[khanaffan]

The main idea here is to attach secondary file to iModel connection e.g. A separate file containing clashes or analysis data. This will allow to use ECSQL to combine data from two or more sources for presentation and reporting purpose.

conn.attachDb("clash.bim", "clashes");
conn.createReader("SELECT p.CodeValue, c.ECInstanceId FROM main.plant.PIPE p JOIN clashes.cl.Clash c ON p.ECInstanceId = c.ElementId ")

conn.detachDb("clashes");
