add fltk-form example

quick fl2rust + fltk-form example

The only thing I am unsure about is the "dependencies" line I added in the Cargo.toml is that the right way to add them?

Thanks for the PR. The dependency to fltk-form and fltk-form-derive should be added in the [dev-dependencies] since, like fltk, they're only used in the examples.

Update the README.md more when you have the link to the source code, and add any information you want. I put the fltk-form section at the end of the README, feel free to change it!

Looks good 👍

Thanks! I might create more to show a more detailed emit(), or how to access ui elements in more detail

[MoAlyousef]

Sounds good
