JasonDB v0.2 Roadmap

[w-henderson]

JasonDB v0.2 is a complete rewrite from scratch, replacing the previous dodgy code which has now been placed in the legacy branch. A very bare-bones implementation has been completed, and this issue details the features and fixes needed to flesh it out before we can publish it.

Checklist

• Write inline documentation for the crate #6
• Add migration options for changing datatype #7
• Add more flexible methods for creating and opening databases #8
• Optimise more queries using secondary indexes #9
• Optimise the crate generally using profiling #10

If any more features come up, they will be added here.
