Update to 1.01
Add missing DEPENDS.

Upstream changes:
1.01
	15 Aug 2017
	- Move Math::Utils dependancy from 1.06 to 1.10. A test
	  was failing in 21-secondd.t because the older version's
	  pl_evaluate() wasn't handling lists back then.
1.00
	9 Aug 2017
	- Add tests, more POD clean-up, send to CPAN.
	18 Jul 2017
	- Add references for the central and forward difference
	  methods.
	- Have not been able to find a reference for the second
	  derivative difference method, annoyingly.
	- Minimum perl version set to 5.10.1.
	17 Jul 2017
	- Added a forward difference approximation method (bug was filed
	  for this as user Maitraya Baliyan was expecting it instead of
	  the central difference approximation method that Derivative1()
	  used).
	- Added names forwarddiff() and centraldiff() for export.
	  Derivative1() is aliased to centraldiff(), so as not to break
	  old code.
	- Likewise, seconddx() is now the exported name of the second
	  derivative difference method, with Derivative2() aliased to it.
	- There is now an EXPORT tag, ':all'.
	- POD is more descriptive, has more examples, and uses the
	  new names.
