# Scoring logic 
# To each finger we associate a score:
# thumbs: 1
# index: 1
# middle: 2
# ring: 3
# pinky: 4
#
# To each required motion we add 1 point
# so that it means that all home row letters will
# get 0 as increment (no motion).
# Every letter on top row will receive the score 
# associated with the finger + 1.
# Same for the bottom row. 
# Index fingers are special cased as they have one more
# column each  (T-G-B and Y-H-N), so they receive +1 for this column.
# Pinky fingers get +1 for each non-column letter (such as [, |, TAB ecc).
# Number row gets +2
# All other chars get +2
# Capital letters get +2
