created build directory
add header dependencies
Added collect.c to simply collect data for graph
Moved num_readings to header and decreased it

-Decreasing this value leads to faster response but
 also increases noise in the signal
-May be able to make read() more intelligent by quitting after a number
 of readings above a threshold
Main.c now outputs HIGH on each button press

-Currently, bouncing isn't much of an issue
 With a high enough NUMREADINGS, only one HIGH is registered for each touch
