Detailed Description

Reads CSV (comma-separated values) text files.

Input file is assumed to begin with a header (the intended observation names, separated by commas). The rest of the file should consist of comma-separated values. This functions similarly to Inject, except that it reads from a file instead of from a control; this can be useful to add metadata (from a file) to improve the machine learning.

Controls:

• mrs_string/filename [w] : name of file to read
• mrs_bool/hasData [r] : is there any data left?
• mrs_natural/size [r] : filesize in samples
