Add some TODO's
Mark WIP in TODO
Add boundary and seek exact commands

To find boundary of a phrase :
- ensure buffer in synchronized
- "seek exact {line,col}" to place cursor on the current phrase
- "boundary" to retrieve a pair [{line,col},{line,col}]
  or null if there is no phrase
In seek position command, use seek_backward rather than custom code
