Arjuna 0.8.14

Primary changes available in this build are related to Widgets, Gui exceptions, test name representation in reports and CLI switches.

• Added arjex_internals examples project to create example code that reflects/tests internal workings of Arjuna.
• CLI changes based on community discussion
  • c/consider prefix changed to i/include
  • i/ignore prefix changed to e/exclude
  • --enumerate-only change to --dry-run
• My.repr method is used for including test data in test name. No more of the staple 'my0' in the names.
• Fix in PyTestHooks. Still need to look for a better solution. request object is not retrievable when error happens in fixture.
• To support nested element finding across all With locators that use XPath, "." is automatically pre-fixed if not present.
• New named exceptions introduced for better information: GuiNotLoadedError, GuiLabelNotPresentError, GuiNamespaceLoadingError
• Concept of root element introduced for Widget.
  • Widget takes a keyword argument 'root_element_locators' in its __init__method.
  • You can specify a single locator (With object) or a list of locators.
  • You can also specifiy it in corresponding GNS file with a special label: root
  • If both are specified, then one passed in init overrides the GNS entry.
  • If root element is specified in any of the above manner, it is used to find elements when factory methods of Widget are used (e.g. .element())
  • If root element is NOT specified, automator is used as the finder.
• Test Object Space (earlier called Shared Spaces)
  • my.modules_shared_space is changed to my.module.space for better code structure.
  • my.space in test refers to the current test's scope.
  • In fixtures, request.space refers to the scope as per the fixture scope.
  • With my.space, and request.space, storing is done for scope, retrieval is from current test object up the parent chain.
• Doc links in main README.md made abolsute because for PyPi.
