def python::rootplot::utilities::replace	(		string,
			replacements
	)

Define additional helping functions.

Modify a string based on a list of patterns and substitutions.

replacements should be a list of two-entry tuples, the first entry giving
a string to search for and the second entry giving the string with which
to replace it.  If replacements includes a pattern entry containing
'use_regexp', then all patterns will be treated as regular expressions
using re.sub.
