1.0 ideas and tracking

[bugadani]

Use this issue to collect issues, ideas towards a 1.0 release.

Current open topics:

• Naming. The inclusion of SlotMap will make the Slots name even less descriptive and useful.

To Do:

• Fixed size SlotMap implementation based on this talk
• Optimize the next_free member (Reduce memory footprint #13)
• Iterator support (Relaxed may have mutable)
• Less cluttered API (Clean up the required amount of trait bounds #12)
• Option for a more relaxed access mode (Different access modes based on type #10 or Split RawSlots and Slots #11 UnrestrictedSlots implementation #17)
• Documentation improvements
