示例1: main
/**
* Fetches muse-io udp packets from port localhost:4545 and reads OSC paths:
* /muse/elements/delta_relative
* /muse/elements/theta_relative
* /muse/elements/alpha_relative
* /muse/elements/beta_relative
* /muse/elements/gamma_relative
*
* Calculates mean delta, theta, alpha, beta and gamma values (and st.dev.)
* from all channels and which /muse/elements/is_good value is >= 0.5.
* If there are no good values at all, reports 0.5 value and maximum st.dev.
* (of uniform distribution between [0,1])
*
* Also measures:
* /muse/elements/experimental/concentration
* /muse/elements/experimental/mellow
