Create a sample buffer.

Create a sample buffer.
Sizenumber
Size of internal buffer. Must be a constant integer. Any changes during program execution will be ignored. Maximum size is 255. Odd sizes results in a 'real' middle element and will be a bit faster. Even sizes takes the average of the two middle elements as median.
