Given the current sample count (which can be extracted from ProcessData::processContext->projectTimeSamples) returns the number of samples for the next bar boundary.

Example: with a tempo of 120 (4/4), and a sample rate of 48000, each bar is 96000 samples. 

getNextBarSampleCount(52123, 120) == 96000; // 1 bar
getNextBarSampleCount(600000, 120) == 672000; // 7 bars
getNextBarSampleCount(672000, 120) == 672000; // 7 bars
getNextBarSampleCount(672001, 120) == 768000; // 8 bars
