made sure every caller of getIdentifier can handle an array. getIdentifier now always returns an array.

Updated manual pages and changed documentation naming convention (from process to parse) to follow the API

started refactoring to final mapper structure for 1.0. different mapping strategies are factored out as separate strategy classes instead of inheritance.

Second parameter support in Doctrine_Pager::setCountQuery and added new method: Doctrine_Pager::getResultsInPage(), which returns the numbers of itens in current page

Merged 3786 (removed is_numeric check from convert boolean method, when array is passed as parameter)

added tests for Collection. also fixed a bug with serialization in collections. added copyright header to the two new testfiles

Added tests for Doctrine_Access. It uses annotations for exceptions and to mark functions as tests. Also changed some logic in access and implementing classes to make the abstraction a little bit more solid
