[DOCUMENTATION] Add User Documentation for Strategies #77
Description
Current situation
The documentation needs to be improved. The strategies are a core element of PlatynUI and need a proper documentation from the user perspective.
Describe the solution you'd like
The user documentation has a section that explains the following aspects
- what is a strategy (for PlatynUI)
- list of all the strategies, their purposes, when and how to use them, which controls are available
- examples of usage, screenshots/images to better explain
- provide a working Robot Framework example with a test app (e.g. KeePass, self-written program in python/QT) for each strategy. These examples also serve as acceptance tests for PlatynUI
