Simple material-style flyout menus for Android. There are many flyout type menus for Android, but this one is mine.
Move minSdkSupport down to 14
All FlyoutMenuView attributes are now prefixed with fm, such that borderSize becomes fmBorderSize, etc. This is to avoid namespace collisions with other libraries.
Add support going back to API 16.
Note, this version now uses the attribute app::buttonSize to specify the size of the trigger button. Previous versions fit the button to the largest circle contained in the explicit layout_width/layout_height. Now, layout_width and layout_height should be set to wrap_content (or whatever)
