Optional params for facet range

Removed all phpdoc packages and subpackages. Obsolete now namespaces are used, removing them simplifies development and maintenance

- fixes varname in client class

- fixed namespaces in testcases
- made morelikethis query test independent of select query test

Also updated unittest

Unittests not yet updated...

Most unittests updated, plugins and plugin unittests still need some work.

Moved requestbuilder and responseparser mappings out of the select query class and into the query component classes

Updated examples for the reorganized library files. Most examples now work, but some might still need some work.
