After this change, Writer/Word2007 is 100% covered.
One source change is required. Writer/Word2007/Style/AbstractStyle
has incorrectly searched Measurement Array using
in_array (which searches values) rather than array_key_exists (keys).
There was no test for this, and now there is.
3 changes in tests/PhpWord/_includes are borrowed from "ODT Changes"
(pull request 1796, not yet merged)
and "Fix PHPUnit Tests" (pull request 1771,
merged after work on this change was started).
Writer/Word2007/ElementTest was becoming too unwieldy. Tests for
Chart and FormFields were moved to their own members.
