Generic copier templates

The base configuration provides generic copier classes that you can extend to simplify a copy data implementation. Many of the copiers in the base configuration extend these copier classes.

The generic copier classes are:

Copier	Description
`AddressCopier`	`extends Copier`
`AllConditionCopier`	`extends GroupingCompositeCopier`
`AllCoverageCopier`	`extends GroupingCompositeCopier`
`AllExclusionCopier`	`extends GroupingCompositeCopier`
`AllExistingCoverageCopier`	`extends GroupingCompositeCopier`
`AllExposureCopier`	`extends GroupingCompositeCopier`
`AllRemovingCoverageCopier`	`extends GroupingCompositeCopier`
`ClausePatternCopier`	`extends Copier`, and can be used on most policy lines for copying line level coverages
