Parse data only once

[layik]

The TGVE does some heavy processing. Currently various components do parsing during interactions by user. All this can be done by some preprocessing/parsing of the data. All subsequent interactions should be drawn from such preprocessing for performance boost.

Two ways of making sure this happens:

1. central: function to parse data once: drawback here is unnecessary processing
2. react: let react handle components that parse the data: above draw back is taken care of, only when needed processing is done by various components.
