New ported DaisyExamples examples and other goodies

[clevelandmusicco]

Hey, folks. The list of examples continues to grow with 6 newly-added ported examples from DaisyExamples:

• BasicChorus - Tweakable mono chorus effect
• BasicFlanger - Simple flanger effect with adjustable delay and feedback
• BasicMultiDelay - 3 delay lines, each with tweakable time and feedback
• BasicPhaser - Flexible phaser with 1-8 stages (poles)
• BasicSpringReverb - Straightforward spring reverb effect
• BasicTremolo - Tremolo ... as basic as it gets

We've also added a fun and funky 3-voice chorus in the TriChorus example.

As always, pull requests are welcome. Have fun!
