Detailed Description

A helper class for advance operators.

The intent for this class is to allow some "Matlab" like expressions.

Example:
// C++
Buffer b1;
b1 << "california.wav";
// limit anthing outsize of +/- 0.3
b1(b1 > 0.3) = 0.3;
b1(b1 < -0.3) = -0.3;
// Python
b1 = Buffer()
b1 << "california.wav"
b1(b1 > 0.3).set(0.3)
b1(b1 < -0.3).set(-0.3)
