Feature Suggestion: Suppress stdout display within config

[jranalli]

I'd propose that you add a config option config['reg_printerror'] or similar to allow suppression of pm.utility.print_error and pm.utility.print_warn output to the stdout. Those outputs are helpful when doing command line programming, but can be an obstacle to try: except: structures meant to handle the error.

Example: To generate a constant entropy line on a pv diagram, you pass a list of pressures at a fixed entropy to T_s(p=p, s=s). There are some conditions where the list of pressures would make T exceed the maximum allowable T, so you could use a try: except pm.utility.PMParamError: structure to catch the error and retry with a limited pressure range in that case. It's useful not to have the error hit the stdout, since it's being handled. This is especially true when we're doing this for cgi figures in pyrodoc, where the stdout is generating useful code/image data.

This is good, and it is easy to do. I'll leave the issue open until the next major release.

This is now written in to the planned release for 2.2.0. There will be configuration parameters that allow users to mute error and warning messages. Thanks for the idea!
