Pterasoftware

This release fixes a few small bugs that caused the `print_unsteady_results` method to fail and produce inaccurate results.

This release is a major development in PteraSoftware usability and accessibility.

It adds a GUI capability and .exe installer to allow users to experience the future direction and capability of the software. As of this release, the GUI is still a work in progress, and only the examples that can be found in the "Help" bar can be utilized. Additionally, there is now a video tutorial for installing Ptera Software's codebase. See the ReadMe for more details!

This release fixes an issue in the force calculations for unsteady simulations.

This release implements a new feature: automatic convergence analysis for steady and unsteady problems! Now, you can check that your simulations use a fine enough mesh, an appropriate wake model, and are simulating for long enough. See the `convergence.py` module and the new example scripts for more details.

This release implements a new feature: automatic trim analysis! Now, you can search for the trim state of steady and unsteady problems with one airplane. See the trim.py module and the new example scripts for more details.

This hotfix release fixes two bugs in the `output.py` functions. The first bug caused the `animate` and `draw` functions to have incorrect scalar bar ranges. The second problem was that the `animate` method displayed fast movement unnaturally slowly. This release also corrects minor errors in the validation and formation-flight scripts.
