Translate a pyquil program to a single einsum call

	## einsum_compiler.py
	##
	## What it is
	## ----------
	##
	## Numpy has a standard function, einsum, which can be used to evaluate large
	## nested summations. Here we show how to translate a pyQuil program consisting
	## of only gate applications to a single einsum call.

Regular Expressions in Python

	"""Regular expression parser and interpreter.

	One may check whether a string s matches a regular expression r by using the
	`matches` function. To construct a regular expression object from its compact
	textual form, use the `parse` function.

	As a combined example,

	>>> r = parse("a\|b*(c)")
	>>> matches(r, "bbbc")
