Completed functionality of hexToDescrip.

Now have capacity to input a hex value and output descriptors of songs matching that color, based on our initial seeds of the six primary RGB colors (Red, Yellow, Green, Cyan, Blue, Magenta) based on somewhat arbitrary values we gave them for descriptors of Danceability, Energy, Tempo, Mode, and Loudness. Takes into account changes/shifts in saturation and brightness, which impact the danceability, energy, and loudness.

Shifted to a SQLite structure to hold our initial seeded primary colors and their descriptor values.
