	Like cut, but for CSVs. To be used from a shell command line.

	Note that fields are zero-based, as opposed to 'cut' where they are 1-based.

	Should use something better than getopt, but this works...

	Usage:
	csvcut foobar.csv

Command line 'cut' utility that can handle csv quoting. This allows proper handling of fields that contain delimiters, both field and record delimiters like commas and newlines. Thanks to github.com/JoeGermuska for the initial version of the code.

Searches a graph and yields all the minimum spanning trees in order of increasing cost. This could be used to solve minimum spanning trees with constraints by yielding trees until we reach the first one which satisfies a constraint. For example it could solve the degree constrained minimum spanning tree DCMST
